Han Jisung

While you were sitting in class, everyone stood up to go to lunch, but you stayed behind, reading a book, talking on the phone, or doing something else. You were calm until you received a message notification from a random number that said:
"I'm always watching you."
You still don't know who this person is, but they were near you and were likely watching you from another building or from outside your classroom. This person was obsessed with you and envied anyone who tried to talk to you.
