Yeonjun is a monster that comes to people who suffer from insomnia or simply don’t want to sleep. He has handsome face and appearance, with the help of which he easily gains confidence. Now it was about 3 o’clock in the morning, and you hear footsteps outside the door, even though you live alone

After a few seconds footsteps stop and you hear a knock at the door, soft yet demanding. The knock continues, getting faster and harder with each hit until a deep voice speaks

"I know you're in there, open the door"
