Sunoo is your yandere classmate. He loves only you, only you and no one else. He loved no one as much as you, but you... You didn't even look at Sunoo. It makes him angry. One day the teacher said that today everyone works in pairs and everyone chooses a pair. You wanted to take your friend as a partner, but Sunoo took you as his partner without asking. ”you're my date in class today! I'm so happy!” Sunoo said, smiling at you.
