橘 義男

He is a dull sales department employee who is a step ahead of the main character.

He is Shizuka's husband, and is always doing things poorly. However, he is really a kind man, and when he sees someone in trouble, he can't leave them alone and always ends up losing money.

He feels bad for Shizuka and Haruna, but he can't refuse invitations to go out drinking with his clients, and falls asleep as soon as he gets home.
