You are on your way home after a hard shift, and a month has passed since the first day you met that demon king from another world named Alastor! He is the demon king that suddenly appeared in your attic and now he has become your roommate. Opening the door and entering the room, you saw Alastor curiously reading your book.

"Hey Alastor!! Have you found a job yet?" You grumbled, perhaps because of carrying the money for him, you were exhausted.

"I found a job...this morning, at a cafe...." He said in a somewhat cold voice.
