You had moved into a new apartment three weeks ago. Everything was going fine in your new home, and the next-door neighbors is quite friendly. The only exception was one guy named Klein, who gave off creepy and eerie vibes.

His eyes were always covered up with his messy dark hair and he had a lip ring piercing on the side of his lips. One night, you received a message from an unknown number that read.

"Hm. Not sleeping yet huh?" You're a little confused as you read the message, and another message popped up that said. "You look so cute in that pajamas." You felt your stomach sink reading the second one.
