Maybe this person I'll be here to fill your good days from now on. ioi sejeong chaeyeon Sechae chaejeong produce101

This person

Sejeong // Chaeyeon

“Maybe it's this person. will be right here

Come fill your days with good things from now on."


This person

                                                        Sejeong // Chaeyeon

If in this world People who are important to life besides mother and family.

The person Sejeong wants to hug when times are tough.

It would probably be Jung Chaeyeon.

only one person

Kim Sejeong couldn't deny that. The beautiful face that was still and calm didn't reveal those feelings. Instead, she was so strangely attracted that Sejeong couldn't take her eyes off Jung Chaeyeon for even a second when Chaeyeon walked in and appeared as a former member of the group.

DIA

Before starting the program

Produce101

Until it became a sensation and was talked about by outsiders And the other contestants always attacked Chaeyeon for this matter. That it's not fair, after debuting, why would you compete? Even though Kim Sejeong herself wasn't very close to Jung Chaeyeon at that time, she had to admit it.

Jung Chaeyeon has completely entered Sejeong's mind.

Even when practicing songs on the show Kim Sejeong also secretly walks by the room where Chaeyeon practices frequently. I don't know if Chaeyeon will notice or not that this Sejeong is trying to hang around. Whether it was flirting with Ki Hee Hyun and trying to sit close to her sometimes, or even secretly watching Chaeyeon practice dancing late at night alone in the practice room, Sejeong always noticed how much pressure Chaeyeon had to carry. People who have various expectations of you

The accusations never end. Sejeong knew this all along even though Chaeyeon didn't know.

How much does this Sejeong secretly care about Chaeyeon?

Especially on the day the results are announced. I heard Jung Chae Yeon's name being called. I don't know why but she was so happy that she forgot. Just ran in to congratulate Jung Chaeyeon. Thinking back, Sejeong couldn't help but secretly feel a little embarrassed that he wasn't that close to Chaeyeon. But she was even happier than herself, probably because Sejeong saw Chaeyeon's effort.

and has always supported me from afar.

Chaeyeon's determination finally paid off.

Chaeyeon debuted as a member.

IOI  

Including Sejong himself.

Sejeong always smiles when she thinks about the first time she joined the group with Jung Chaeyeon. And that made the two of us who used to know each other superficially begin to gradually become friends. They become closer the more Sejeong is around Jung Chaeyeon. The left side of his heart began to beat rapidly for no apparent reason. Just words of introduction on the day we met after the results were announced on the first day.

It still reverberates in Sejong's head. No matter what time

“Hello, Sejeong hyung.”

“Hello Chaeyeon, ah, let's fight from now on. Let's work hard.”

“Yes, Sejeong hyung too.”

After that, we practiced hard day and night. Even though it was tiring, it made the eleven of us closer together, including Sejeong herself, who was closer to Jung Chaeyeon than before. Moreover, Sejeong herself learned that Chaeyeon was preparing to return to the group.

DIA

Again, Chaeyeon had to work twice as hard, causing her to sleep in the dorm during that time. Jung Chae Yeon became the person who always came back late.

"Aren't you asleep yet?" a soft voice called out. from Chaeyeon after returning from rehearsal with the company. Looking into the kitchen where the light was on, you saw the figure of Kim Sejeong, who was busy boiling ramen.

"Oh, I'm not sleepy yet. I'm just hungry late at night."

Sejeong looked at Jung Chaeyeon who put the bag she was carrying down next to her. on the table, exhausted, so he slowly walked over to open the refrigerator and picked up a water bottle. Before reaching out and taking out a glass of water, he poured cold water into the glass and handed it to Chaeyeon who was sitting.

"Drink something cool and you'll relieve your tiredness."

Chaeyeon reached out and took the glass from Sejeong before drinking the cold water completely. Sejeong couldn't help but smile when she saw Chaeyeon's smile, which returned her sweet smile with a pout on her face. To ask you to pour me that cold water again

“Are you hungry?”

“I'm hungry.”

"Then wait a moment. I'm about to finish cooking the ramen."

Sejeong immediately turned to look at the ramyeon before putting on heat-resistant gloves to lift the pot of freshly boiled ramyeon. Put it in the middle of the table. He picked up two pairs of chopsticks and sat down across from Chaeyeon. Handing chopsticks to the younger person

“I'll open it,” Sejeong said, reaching out to pick up the lid. Look at Chaeyeon's face, who is now acting very excited at the ramyeon standing in front of her. Sejeong then slowly Open the ramen lid. Hot smoke rose up until it hit the nostrils and sent a smell everywhere. Jung Chae Yeon couldn't help but hurriedly bent down to smell it. Which happened to coincide with Sejeong's heart, who was bowing his head at the same time.

“Oh!”

Chaeyeon raised her head slightly. before gently holding his own head Along with the sound of laughter, including the older man who was holding his own head. Before the silence slowly fades It appeared immediately when Sejeong locked eyes with Chaeyeon. With the dim lights Who only saw the two of us and the atmosphere seems to be pleasing Sejeong couldn't help but slowly.

He reached his face closer and closer to Chaeyeon, causing the younger person sitting there to become restless and his heart skip a beat. Seeing Sejong's faces only a slight distance apart It will make our lips close together Sejeong looked at the pretty face. I couldn't help but laugh when I saw Chaeyeon close her eyes. He lifted his face to wait for her kiss.

“Chae doesn't eat ramen?”

Chaeyeon, who had her eyes closed, was startled when she saw Sejeong's face, a mischievous smile on her face. She pretended to hide her embarrassment by slamming the elder's shoulder once before pulling away her own face. far

“Oh, why did you hit me?

"So, why are you teasing me?"

Chaeyeon shouted angrily and immediately lifted up her chopsticks to scoop ramyun into her mouth. Sejeong bent down to rest her chin, looking at the younger man's face showing anger by eagerly eating ramyun. I don't know why Saejeong himself likes to provoke Chaeyeon so often. Maybe it's because of his silly face. The things Chaeyeon does when she's angry

It turned out to be the cutest picture for Sejeong.

“Are you upset? You think you're going to kiss me?” Sejeong teased Chaeyeon again, which made Chaeyeon quickly turn around and look at Sejeong, her eyes widening before choking on water.

“Here, you ate all this mess.” Sejeong quickly reached for a few tissues and pulled out a few sheets before handing them to Chaeyeon to wipe up the choked water and mess on her shirt. Chaeyeon is always like this. What do you like to eat? Really like a little child all the time. This is another side of Jung Chaeyeon that is rarely shown to anyone.

There were only people in the band.

And Sejeong is the one I see most often.

"Well, I like to tease you. Seriously, why do you like to tease me so much?"

Sejeong heard this and secretly smiled at the question of a complainer who couldn't help but have a heart in front of him.

"That's how I like it. If I don't love you, I won't tease you, you know?"

Even after IOI's promotions ended, news of Chaeyeon's comeback in the name of

DIA 

And the trend came back in again. Question: The various comments on netizens about Chaeyeon became a strong trend all over, and that made Sejeong, who was following and reading the news, even more worried about Chaeyeon.

Until now, I don't know what will happen.

Sejeong knows that Chaeyeon tends to be a person who likes to keep things in her heart, saying it's okay, but her heart likes to think too much.

Even these bad comments

Chaeyoung must have read it all.

Sometimes Sejong thinks about why people always judge things based on the news first.

without caring about how sad the people in the news are

Chaeyeon always intends to do everything, no matter how

IOI

or

DIA

“Sejeong hyung, did I dance well?”

Chaeyeon asked as she was practicing her dance for a promotional song in IOI's living room. Today was the group's first day of rest after promoting almost together for two weeks, so everyone took the opportunity to take the day off. Let's go on a trip. But Jung Chaeyeon is the only one who lives during this time to practice beautiful songs until next month.

Chaeyeon herself has to promote as a group.

DIA 

And that's why Sejeong wanted to sit and cheer on Chaeyeon in the dorm.

So I didn't go anywhere like everyone else.

“Dances well, better than me.”

Sejeong looked up from her book and looked at Chaeyeon through her round glasses that she always wore when she wasn't going out in the dorm. Because Sejeong's eyesight is shortsighted, he must always wear these glasses. Moreover, she herself is a person who likes to read books from time immemorial. So he took the opportunity to read a book in the living room while watching Chaeyeon practice.

“Really? I don't think you're watching me more.” Chaeyeon looked at Sejeong, who responded indifferently when she saw her sitting on the sofa reading a book. Chaeyeon didn't want to believe her words because Sejeong might be teasing her answer. To make her comfortable before Chaeyeon decided to practice dancing again by herself.

“This position, you have to do this position, oh!! Chaeyeon immediately fell to the ground. When standing and dancing, he accidentally lost control and twisted his own ankle. Sejeong saw this and quickly got up on the sofa in annoyance before gently cradling the younger man onto the sofa. Chaeyeon sat and looked at Sejeong who was slowly fading. Taking off her dance practice shoes followed by taking off her socks. Before rushing to the refrigerator in the kitchen, he immediately put the ice pack on his ankle.

“Compress it so it doesn't swell,” Sejeong said as he applied ice to the area that was starting to swell slightly. Sejeong looked up at Chaeyeon, who was starting to feel worried about her ankle. Probably afraid that I wouldn't be able to continue practicing. before sending a consoling smile like the person in front of you

“It doesn't matter if you rest it will get better. Be careful later, understand?”

"I don't want us to get hurt."

Even Sejong said so In a few hours, Chaeyeon immediately resumed practicing, and Sejeong couldn't help but worry. Chaeyeon was even more worried about the news. Until having to practice this hard even though Sejeong had told Chaeyeon many times not to read those bad messages.

Because it was a message that didn't come out.

From someone who truly loves you

But Jung Chae Yeon is still her stubborn younger sibling. Reading those messages to the point where I often had to sneak away and cry quietly alone.

And that makes people who love you like Sejong

feel pain

Sejeong always sits and looks at her phone, typing messages to Chaeyeon. Now there's been too much news after Chaeyeon started promoting with the group.

Dia  

Due to their tight schedules, Sejeong and Chaeyeon hadn't seen each other for the past several days, and that made Sejeong even more nervous when she saw that Jung Chaeyeon hadn't responded to any of her messages.

Chaeyeon had never been like this before.

Sejeong sat staring at his cell phone for a moment before it rang. That made Sejeong immediately grab her phone and look at it before being disappointed when she saw an incoming message from Ki Hee Hyun.

Ki Hee Hyun : Sejeong

Sejeong: What?

Ki Hee Hyun: Chaeyeon disappeared.

A message appears. That made Sejong immediately get up and leave the room. He ran onto the bus that was driving outside. Get off at the sign in front of MBK Company. before rushing straight to the practice room

DIA  

that she had visited long ago Before meeting close friend Ki Hee Yeon from when they competed together, standing in the room with the members.

But there was no shadow of the person Sejong was looking for.

“Where has Chaeyeon gone?”

“Um, it's Chapa.. Oops.” Ki Hee Yeon's hand reached up to cover Ye Bin's mouth just in time before she could interject.

“Last seen in Han River Park, now unable to contact. You hurry and go, Sejeong.” Sejeong immediately ran out when he learned of the younger man's location. And that made Sejong extremely nervous.

What do you do in the evening? At the river

Fortunately, the public park was not too far from Chaeyeon's company. Sejeong had already run in less than ten minutes. He quickly walked around looking for the younger, familiar figure before finding Chaeyeon standing with her head bowed. Located next to the pond of Sarathan Park.

“Chaeyeon!! What are you doing?” Sejeong immediately rushed to grab Chaeyeon and pull her out of the pond, but she lost her control when she saw Sejeong rushing towards her.

Closet!!

The sound of water splashing sounded as the two figures fell like a pond in the middle of a public garden.

“What are you doing to me?!” Chaeyeon was now falling into the pond with Sejeong lying on the bottom, supporting the weight of the person above her. But luckily the pond they fell into was shallow. Therefore, it did not cause them to sink much, but instead only made both bodies wet.

“Is this a shallow pond?”

"That's right. It's all wet. Can you let me go?"

Chaeyeon looked at Sejeong's face before moving her eyes to look at her hand that was hugging her, even though Jung Chaeyeon secretly felt her heart flutter when she was in Sejeong's embrace. Sejeong immediately released his hand. Before the figure above slowly disappeared Slowly he stood up. Turned around in another direction to hide his face that had turned red a moment ago from his older brother. Then gradually

Examine your own body, which is soaked with water. I couldn't help but feel angry. So he turned around and looked into the green eyes. Like the person who stood and smiled and replied. Feeling guilty Even during this period, Chaeyeon herself hasn't seen Kim Sejeong for several days because of the couple's busy schedules.

Even though she secretly misses her very much.

But I didn't expect to meet in this situation.

“So Chaeyeon disappeared, Ki Hee Hyun told me,” Sejeong who slowly got up stammered. When I realized that I was totally at fault for causing Chaeyeon to get wet like this.

Who will know and see him standing there? Looking at the pond And who else knows?

that the oil well is shallow

“Why did I disappear? I just came out to buy a strawberry latte. Then Ki Hee Hyun hyung told me to come stand and wait at the public garden.”

“Ah, then I guess we both got tricked.”

Sejeong said with a light, awkward smile. When Chaeyeon was now looking at him accusingly. Sejeong couldn't breathe. When thinking of the face of close friend Ki Hee Hyun who likes to plan and bully until he loses many times But let's face it, Ki Hee Hyun's evil this time.

It still has a positive effect on Sejong. who met Chaeyeon

Sejeong glanced at Chaeyeon's face, which was now covered in water stains, and decided to take it slow. He reached for the handkerchief that was in his pocket. Luckily, Sejong's handkerchief didn't get wet. So he reached out and pulled the younger person who was standing next to him with a sullen face closer to him, then slowly used a cloth to wipe up the water on Jung Chaeyeon's face.

"I'm sorry I made you all wet."

Chaeyeon looked at Sejeong's face, which was carefully wiping. Her face gently Before Chaeyeon uttered some words that made Sejeong's heart skip a beat immediately.

“Uncle Sejeong, do you like me?”

"Huh?"

That question caused them both to fall into each other's trances. Sejong started to feel that the weather around here was getting hotter. I don't know how it came up. And it was even hotter when Jung Chae Yeon's eyes were staring at her.

“So, do you like me or not?” Chaeyeon brought her face closer and closer, and Sejeong couldn't move away from her. The closer Chaeyeon's face got, the clearer the person's eyes became, the more clearly Sejeong could see them.

“If you don't like me, please stop doing this.”

“Because I like you with all my heart.”

Chaeyeon said as she hurriedly walked away, as if it were different from what she had originally thought, that she would be the one expecting an answer from the elder. But why did it turn out that she was the one who confessed her love for him first?

And that made Chaeyeon feel the most embarrassed.

“Chaeyeon! ”

Porn!!

“Be careful of the pole, you might not be in time.”

Sejeong rushed to see the younger man who had walked away before Sejeong could reply. He walked away slowly. Without looking, I realized that I was walking straight into an electric pole. Sejeong slowly picked up Chaeyeon's face and looked at the mark on her forehead where Chaeyeon was currently frowning. He complained of a slight pain in his head. Chae Yeon's stupid expression made Sejeong unable to hold back her laughter at Jung Chae Yeon's stupidity.

"Does it hurt? Walking into a pole?"

“That's me!! I accidentally confessed my love to you first. So I walked into a pillar instead of confessing first. You idiot."

"Please forgive me again, man."

Sejeong bent down to one side and looked at Chaeyeon's face, whose face was now starting to turn red with a slight blush on her cheeks. Ever since she was born, Chaeyeon had never felt this shy and embarrassed before. Sejeong then reached out and gently rubbed the younger's head to comfort him. And that made Sejeong laugh again when he learned that Chaeyeon was mad at herself for not confessing her love first. In fact, Sejong secretly had thought about how to confess many times.

But I didn't think Chaeyeon would start speaking first.

When it wasn't romantic at all

“Then forget about the previous incident for now.”

Sejeong reached out and covered Chaeyeon's eyes. Before opening her hand again, Chaeyeon slowly opened her eyes, and that allowed Chaeyeon to see her older sister's face more closely than before. And that made Chaeyeon's heart beat irregularly.

When meeting Kim Sejeong's serious eyes

“I like Chaeyeon. I liked it from the beginning before the show. I've always liked it.

And Chaeyeon, do you like me or not?”

“Oh, and don't deny it...because of you.

I like Chaeyeon with all my heart.”

Chaeyeon, who was deeply touched by her older brother's confession, immediately smiled when Sejeong said the same words she had said before. Does this person think of teasing you all the time? before slamming his hand down hard.

"Oh, why did you hit me again?"

“Well, I always like to tease you. Are you a psychopath or something? You like to get hit!!”

Sejeong quickly tried to grab Chaeyeon's hand who was about to hit her. before pulling himself closer and hugged Chaeyeon again Until the person who had been stubborn just a moment ago quieted down. Sejeong looked at Chaeyeon, smiling at her shy expression, before slowly leaning his head down to rest on Chaeyeon's shoulder. The younger one responded by wrapping his hand around the older one's waist and resting his head on Sejong's broad shoulder.

The warmth from the embrace was something Chaeyeon couldn't deny. That it's always good to have this irritating Kim Sejong beside you. in difficult times

"I like you, you know? Because you are

presence ofwill 

my"

“Wait, what does that mean?”

“You don't have to know!!

FIN

“Sejeong hyung, let's think of a name.” Chaeyeon looked up at her lover, who was currently lying on her lap on the sofa in the guest room when the series she was watching right now saw the hero and heroine having names. specific name Waiting to call each other

Until Chaeyeon herself wanted to have a name like the other couples.

“How about calling Chaeyeon? It's easy. Why is it complicated?” Sejeong looked up at the book, looked at the face of the person who started to look dissatisfied and immediately stood up from his lap. Sejeong sighed slowly. Because that is indicating that his own boyfriend is now starting to send signs of anger to Sejeong. This person must start to feel sorry for the person in front of him again, so Sejong slowly Put the book aside. before turning to look at Chaeyeon who was now making a puffy fish face.

"So, what should I call you, Chaeyeon, the fool? Oh my!!"

“Why do you always have to tease me?”

"Then I'll call you Chan-chan."

“As for Chae, is it okay to call me Seseni?”

“That's funny, no, let's call it the same thing,” Chaeyeon smiled and laughed. When thinking of strange names that Sejong set up a conversation with before abandoning the idea Falling down to sleep on Sejeong's lap again.

“I don't know, I'll call it Chan-chan, Osa thought.”

Sejeong lowered his head to look at the person who was looking at him before bending closer until he could feel the younger's breath. Chaeyeon reached out and wrapped her arms around her neck, bringing her closer, and that made Sejeong unable to resist. I can't be fond of it. When Chaeyeon was begging her again which is a cute picture that she always can't resist

“So Ceseney can kiss Chanchanny?”

"okay"

Sejeong met Chaeyeon's eyes looking at him. So he slowly bent down and pressed their lips together. Before moving to the rhythm, tasting the sweetness of the person in front of him for a long time.

Even though the TV sound is louder

But it couldn't make them pull away from each other from the sweetness of that kiss.

Chaeyeon for Sejeong is??

Sejeong: Chan Chan is the person I want to hug when I'm having a hard time.

Chaeyeon is smart or stupid?

Chaeyeon :(smart)*but I like stupid Chaeyeon*

"Do you think I'm stupid?"

"I'm not saying that at all. Oh!! "

I've been away for a long time, haha. Here's one shot for you. Please feel free to criticize this Sechae.
