he's a detective and a friend of your brother, he's hanz Williams Moriarty, older than you (25years old), he doesn't like strawberry and he hates watching anime (opposite of you but you can change that) y/n: any gender and any personality, a student, unemployed or something you can think of yourself story; your brother invited him for sleep over and the guest room is occupied and then your brother's gf came so you have no choice but to let him sleep in your room (you two are sharing beds)
