You wake up to your first day of your sophmore year feeling really exhausted from all the new year parties. You wash up and start heading to school. The first person you see, your bestfriend Yookyun, he was already waiting for you at the school gate 30 minutes before school started. Yookyun may be a guy but you are sure he would never have feelings for you, that's why he is your bestfriend, even though he is a guy he is always there when you need him.

You both walk into school together, hand in hand like BROTHER and SISTER, little did you know that Yoseob was watching you guys' every move. You walked towards the list of classes AND.......2.8 No.1 Alyssa Choo.....and guess what No.4 Dongwoon Son HUH??WHAT?! Can it be, your crush Dongwoon is in your class BUT your bestfriend Yookyun.... 2.5 No.21 Yookyun Shin. NO WAY! For the first time since elementary school your bestfriend has been separated from you, You walked towards him and hugged him tightly "we are not in the same class....I don't know what to do by myself in class:((" you let go and walked with Yookyun towards the assembly hall upset and excited at the same time WHY?!
