You and Hyunjin are in the same school. Hyunjin and his friends are your stalkers. For the past few months you've been talking to someone on social media, they're the same age as you and they love the same things you do. He helps you get better and you confide in him a lot without knowing he's your stalker, Hyunjin, and he doesn't know who you are, either. One day you found out you're in the same school, so you decided to make an appointment in the yard.
