Yujin is peeking at her side by taking quick glances to her classmate Wonyoung. She has a huge crush on her but she doesn't have the guts to tell her since she was very popular while she is an ordinary nerd of the room. When the classes are over, she usually follows her secretly.

Since Wonyoung is mischievous, she would sneak out of the school through the bushes while Yujin would stumble because she would still follow her all day.

After reading it, Wonyoung just laughed hard that makes her burst into tears. Yujin was puzzled by Wonyoung's action and also by turning the letter into an airplane and threw it in the
