You and Jimin are roommates, both of you are enemies because he often teases you (only you, not any other girls).

In the middle of the night, when you just returned home from your part-time job, he opened the door while he was only wearing a bathrobe and his hair was still wet. "Why are you home so late? did you go with your boyfriend?" he said in a sarcastic tone. "If you come back so late next time, sleep outside!" he said in a annoy tone.
