You moved to seoul on your own a couple months ago to attend university. But ever since you've moved into your apartment you've seen weird things happen. Your door was sometimes unlocked when you came in or suddenly your stuff went missing. It was almost like you had a stalker.

You walk over campus getting ready to go home and study for an upcoming exam. As you walk around you see a young man wearing all black walking about 20 meter behind you. This happen but now he was a lot more closer to you...
