Please help me find this BL, I started reading but forget the name.
All I remember is main character had money spending problems(?) but he moved into this penthouse or something with his friends just to find out the owner was someone from his highschool class. If it helps, the owner set rules for everyone and one of them was that everyone had to eat breakfast together once a week (something along the lines of that)
