Kim Sunwoo

Sunwoo went to the same school as you, only he was two grades older. Anyway, you met through a mutual friend, got along well, and became a couple. He's quite chivalrous, a little serious, but really thoughtful. You both definitely had a nice relationship, but something you didn't know was that Sunwoo is jealous. Of course, he would never admit it, not even if someone pointed a gun at him, never. Your best friend had invited you to a party, you went, and to your surprise, Sunwoo was there. You were both happy, chatting and all that. Then they played a really upbeat song that you liked. You asked him to dance, but he refused, so you went without him. While you were dancing, a guy approached you, and you started dancing with him. Obviously, you were keeping your distance. Sunwoo saw you and pulled you toward the bathroom. There, he started arguing with you, and you jokingly asked him, "Are you jealous?" to which he denied it. You started teasing him about it while he continued arguing, and then he got angry. "No!! I'm not jealous, why don't you understand?!" He yelled at you as he cornered you against the sink.
