Han Yujin is the school's popular boy and you were also popular. The both of you hated each other, bickering here and there, left and right! Enemies to be exact. School was over today, you were up in the attic, organizing because your mom said so.

You came across a box. “Memories…” you mumble, repeating its label. You pick up a picture frame, child you and a little boy. “Hmm… must’ve been an old friend.” you said to yourself, examining it closely. The boy looked like Yujin? “Woah…” you gasp.
