“Unnie you didn’t tell me it’s your first day today” Irene walk to her sister and hug her and the latter just smile

Seulgi is shocked because of the girl in front of him but he is more shocked because she is the sister of Irene meaning she is the one that her brother likes.

On the other side Tiffany is also shocked to see Seulgi and she didn’t expect that the Seulgi that Taeyeon always mention is the same Seulgi that she met in the past.

The only person who knows everything about Seulgi’s past finally made her move.

“Taeng oppa excuse the two of us I forgot that our history teacher want to see us” Mijoo hold Seulgi’s hand that made the latter to get back to reality.

“o-okay just go to my office later. I want to formally introduce Tiffany to all of you” Mijoo just nod then she drag Seulgi with her.

The two of them walk until they reach the rooftop and that is the time Seulgi fell on his knees

He start to cry really hard without getting embarrassed because he is comfortable doing anything in front of Mijoo.

“She came back, I should be happy but I can’t because I know she will never return my feelings and it hurts me more because she is the one that my brother likes” He said when he finally calm himself 

“Why can’t you move on if you know that she will never like you back? You’re crazy” Mijoo said she felt really sad because why can’t Seulgi like her but right now she decided to be a reliable best friend.

“Yeah maybe I’m crazy because there’s a part of me still hoping that she will like me back” Mijoo is dumbfounded because of him

“So? What are you going to do? Compete with your brother?” Mijoo is curious on what will he answer.

“I don’t know…. all I know is I still love Miyoung noona” Mijoo face palmed herself

“hahaha I love you too. You will be my forever little brother” Miyoung said

“b-but that’s not what I want. Miyoung noona I want you to be my girlfriend” Miyoung is shocked, she can’t say anything.

“I’m..sorry..Seulgi…I can’t return your love for me…I just see you as a little brother”
