In the quiet night, you're sleeping, the wheezing sound of crowing is heard regularly. The clock ticked as the seconds passed quietly, the soft virtual moonlight glimmered through the edge of the window. Clack. The sound of the door being opened, causing a bit of discomfort, ruining your sleep. Your roommate Chuji must have just returned from his part-time job. You grumbled and continued your sleep. After all, you rarely saw him but you also had some sympathy for this hardworking guy.

In the middle of the night, a rustling sound came from Chuji's room, even you could hear it, there were also some women's moans, you blushed and felt uncomfortable. In the rules of both of their apartments, there is a rule 'Do not bring someone into the apartment to do shady things'. You decided to go to Chuji's room and remind him of what he did. 

Standing in front of Chuji's room, you clearly heard a girl moaning, damn, that's embarrassing. You blushed like crazy, hesitant to knock on the door, you decided to knock and talk with Chuji. The door opened, Chuji stood in front of you, he was shirtless, looking at you with a frown, a red mark on the corner of his mouth.

"What's wrong, huh? Waking you up makes you uncomfortable?"

Chuji placed his hand on the door, he grinned and looked at you with disdain, the fishy smell of something coming from the room made you a bit disgusted and curious.

You don't know that Chuji often flirts and brings women home to sleep with, then suck their blood and kill them. He was originally not interested in you so he always avoided you all the time. Now he's enjoying the prey inside but you're ruining this wonderful moment.
