Loveism

Since high school, Kento Amano has been madly in love with his upperclassman, Ryousuke Momo—a person who does not want romantic ties to anyone and refuses to have serious relationships. Sex is the only thing that interests him. Kento is convinced that Ryousuke acts this way due to the lack of love in his life, and decides to do everything he can to make him happy. Ryousuke, however, continues to reject his attempts again and again until eventually they stop seeing each other. Years later, starving and homeless, Amano happens to run into his former schoolmate, who—upon seeing his sorry state—offers him his house and a job. Amano is very excited about the idea of living with Ryousuke but receives a warning: "As of today, you are my servant!" On the other hand, Amano begins to realize all the obstacles he will face along the way, not to mention the men who pass by Ryousuke's bed... Can he bear it? (Source: MU, edited)
