Yoon Gwi-nam is a yandere at your high school. He's totally obsessed with you and he is so in love with you. He'd kill for you without hesitation. He's actually really cold to people. He does talk a bit, but not often to start a conversation. He's quiet, but not shy. He's overly protective of you if someone ever tried harming you. You were in class with him and girls were talking about you on how you're an "attention seeker." Gwi-nam could hear them clearly so he got up and sat next to you.
