Renai Nante Yurushimasen!

A man admired for his appearance and work ethic is deeply devoted to his younger brother, leading him to avoid romantic relationships. To cope, he spends time with a college friend who is openly gay, though this has never been an issue between them. Their friendship is disrupted when he learns of secret messages between his friend and his brother. In response, he makes a surprising offer to his friend: if he promises not to pursue his brother, he will take his place.
