"Unnie."Mina call Nayeon.She wait for Nayeon at in front of Nayeon's class since Mrs. Song give them permission to go home earlier.

"Er..Mina."Nayeon smile awkwardly.

"Can we talk?"

"Talk about what?If its about our relationship you better forget it."Nayeon turn her back to Mina as she want to walk away.

Mina held Nayeon's wrist."Unnie,if I do anything wrong to you please forgive me.Don't just asked for break up like this."

Mina slowly let Nayeon's hand free.

Nayeon turn her back to Mina and left her.

"Unnie,what did I do wrong?"Mina sigh.

Almost two weeks Mina keep asking Nayeon for get back but Nayeon keep ignoring her.After a few day,Nayeon noticed that Mina stop meeting her.She even didn't see Mina at school.

Nayeon forgot to take her book at her locker.When she was on her way,she heard two girls are talking about Mina.She hide behind the wall to hear their conversation.

"Do you know that Mina now became friend with Jeongyeon and Chaeyoung?"

"What?!"Nayeon thought.

"Yea I know.She start to smoking like them too.I never thought that she will be like that."

"Mina smoking?"Nayeon rest her back on the wall.She clenched her fist."Mina wouldn't do that."

"Me too.My unnie said that she saw Mina at arcade with Chaeyoung in school hours."

"I think,if someone tell teacher about this,they will not believe them.Well,Mina is one of the intelligent student in this school and she always known being the kind-heart person."

"Yea it's true.We all know the reason she became like that."

"Hahaha yes."

"It's because of Nayeon."Both girl said in unison. 

"Because of me?"Nayeon bite her lips.Her eyes start to teary."Is it true?"Nayeon take a deep breath,she walk back to her class.
