"Chungha.....!!!" The first word that Chungha heard when Sejeong came to their room

"Ya! You surprised me" She was shocked because she was changing her clothes when Sejeong came

Sejeong apologized "Sorry I forgot" she smiled and scratched her neck "Wow Chungha, your abs, you look good, y" she added, eyebrows up and down, smirked

"Ya! You ert!" She finished changing her clothes and sat down at her desk

"Why did you go home faster? You didn't go to your club or something like that?" asked Chungha

Sejeong didn't respond, she was thinking of something. Chungha didn't bother to asking her twice, she only did her homework. There was a moment of silence

"Hmmmm... Unnie" Chungha remain silent

"Chungha unnie" the same response

"Kim Chungha unnie" Sejeong called her louder and Chungha responded

"Hmmm why?" She faced her twin "Wait." she just realized Sejeong called her Unnie

"You call me unnie?" 

"Yes, is there something wrong with that? Even though we are twins, but you were born first so you're unnie right?" explained her

"You have a point. But why did you suddenly call me Unnie?" she was confused

"Ah... I know. You need something from me, right?" Chungha spoke, clapping her hands, made Sejeong stop from talking "What's this, this time?"

Sejeong hesitated "Can you help me do a busking this weekend? I need your help, you can show your dance, it will be very helpful for us"

"Why do you need a dance performance? You can do singing for busking"

"Yes I can sing, but it's too ordinary. We need another performance so it won't be boring and it will increase our project score"

They talked about the details, the conversation was quite long and Chungha finally gave a decision.

"Sorry, Sejeong. I think I can't help you this time. I have my plan, I have to finish my paper this week with Heehyun"

"You can finish it later, okay unnie?" It's strange to call her twin unnie, but she has no other choice

"Sorry Sejeong, I can't" Chungha apologized and patted Sejeong's shoulder, back to her study desk.

Sejeong pouted and sulking on her bed. Trying to calm herself and keep her emotions behind the blanket. Chungha spoke

"Do not pouting"

"I don't"

"Don't sulking"

"I don't"

"I know you did it"

"Not"

"Yes, and now you're mad at me" Chungha spoke, but her eyes, hands and brain still working at her paper work. "Sorry Sejeong. I want to help you, but this paper is important to me"

"It's okay" Sejeong said in her blanket, thinking of other plans

Doyeon came to their room "Unnies, dinner is ready" she looked at Chungha

"Thanks Doyeon"

"Where's Sejeong unnie?" she asked to Chungha

"She's under her blanket, probably still pouting" said Chungha with laugh

"I'm not" Sejeong open her blanket

"I don't know what happened here, but let's eat dinner. Taeyeon unnie couldn't stop to bother me if you two still at your room" Doyeon left the room

"Ya! Kim Sejeong, Kim Chungha hurry up. I'm hungry" shouted Nayoung from the dining room

"Don't shout at home" said Taeyeon, after slapping Nayoung's shoulder

"Hehehe sorry unnie" Nayoung gave her a smile

"Let's go eat, Nayoung unnie called us. You need some food to think about your other plan for busking" Chungha pulled her up

"Unnie!" she whined, dragged by her twin

Sejeong was nervous, hoping everything would go smoothly and successfully. Yes. The
