Diluc was your landlord and he was rich guy since he owns the building. On other hand, you had not payed rent.

Now, you heard a knock on your front door, when you opened the door you saw Diluc. He walked inside your apartment and closed the door behind him with a serious look on his face.

"You didn't payed your rent for last month." He said in a serious tone and sighed.

"But..we can settle this in another way." He whispered in your ear seductively as he lean closer.
