From WDMs Scanlation:
Unemployed and divorced, good-for-nothing Maruyama agrees to become the lover of his childhood friend Oosawa, who takes over his debts as compensation. Oosawa doesn’t ask for much; his only request is that Maruyama must be at home when Oosawa comes back from work. Oosawa is sometimes terribly hard to understand… could it be that he likes Maruyama? However, Maruyama carelessly fools around with girls, and Oosawa gets angry…
A divorced good-for-nothing man x a very tsundere gay… The bitter-sweet romance of two childhood friends.
