From Fantasyshrine:

The so-called “Hard-boiled man” famous novelist, Takamura, came to a seaside village and encountered a youth named Midori, who bewitched Takamura with his jade green eyes. But before the cynical novelist realized it, he was dragged into a small hostel ran by Midori’s family! Later, Takamura learned that both Midori and him shared similar heartbreaking childhood experience, yet Midori never lost his faith and trust. In anger and frustration, Takamura violated Midori! How would these two come to terms with their feelings for each other?
