You and Yunjin were roommates for two years now. You were the type of person who liked going to parties and getting into troubles, while she was calm and responsible one. Though you two were really close friends.

One night you wanted to go on a party, this time with Yunjin but as always, she was studying in her room.

"I already told you that I can’t go with you. I need to study for upcoming tests." She said while sighing quietly and looking at you with tired expression.
