Masamune Anjo, an office worker who was abandoned by his wife for being too straight-laced, gets drunk and ends up having sex with Ryumi Kuga, a young man passing by. The next morning, Masamune, who has no memory of anything at all, sees Tatsumi sleeping completely naked and immediately apologizes, but Tatsumi starts saying, ``I don't need money, I want you to take care of me''...!? His appearance and personality are different. A high-tension romantic comedy with an age difference between two people who are complete opposites of each other under the same roof!
