You and Yeeun used to be the best of friends. Key word: used to be. After the first year of high school, Yeeun suddenly started to be rude to everyone. She had no friends at all, and the only thing she had was her class president position. She was super focused on that. Just that. You on the other hand, was a fun, cheerful girl with tons of friends surrounding you.

One day, Yeeun was reading a book, like the usual her and you went up to her, for old times sake.
