Takashi Toono was unsure what to expect when he transferred to Morimori Academy, a private all-boys boarding school located deep in the mountains. However, it's no different from any other boys' school, and since he entered halfway through the year, he feels like an outcast—until the bright and friendly Kyousuke Yaguchi introduces himself. Due to the school's compulsory club policy, Toono chooses to join the low-effort "Photography Club," but the club is not what it seems. Nicknamed the "Yarichin Bitch Club," its members offer sexual services to pent-up boys at the academy—for no reason other than a love of sex. What's worse is his monthly sex quota—and the punishment for failure is severe: the club will forcefully take his innocence. However, as time runs out, Toono is left mortified and out of options. At Toono's side throughout his ordeal is Yaguchi, as well as Yuu Kashima—a fellow transfer student and club member who shares Toono's predicament. While the first years in the club struggle with their sticky dilemma, the club collectively has to deal with sex, secrets, and even stalkers! [Written by MAL Rewrite]

The marriage is just for the appearances, and he ends up getting drunk and spending the night not with his bride but with the sexy ship captain. When the two men meet again in Italy, it is the start of a spectacular love story.

Tetsuhiro Morinaga is in love with his upperclassman Souichi Tatsumi. He even manages to confess his love. Too bad it turns out that Tatsumi is an aggressive, self-centered, and outspoken homophobe. Yet somehow Tetsuhiro managed to fall in love with Tatsumi, the “walking personality disorder,” who is the kind of man who declares that all gay men should be wiped off the face of the planet. An unfortunate accident with an aphrodisiac drug brings the two men physically together against Souichi’s will. The experience has a life-changing effect on both men. But will it ultimately bring them closer, or drive them apart?

On the planet Amoi, a person's status is primarily dictated by the color of their hair. This society is run by the AI supercomputer known as Jupiter and its governing board of perfect blondes, referred to as Blondies, living in the capital city of Tanagura. However, the darker-haired humans live out their lives in the golden "pleasure city" of Midas and its outlying slum Ceres. They are known as "mongrels," and most cannot progress out of the slums. Three years ago, a boy named Riki disappeared from the slums of Ceres. Once the revered leader of the gang Bison, a sudden encounter with an elite Blondie, Iason Mink, forced Riki to abandon everything he had cultivated. The boy was snatched from his home and forced to become Iason's pet. Riki has spent the past three years enduring numerous blows to his pride, his time in Tanagura nothing but a form of torture. Now that Riki has returned, Bison once again rallies behind him. The risk he finds himself in, however, is much greater than ever before—there is always someone ready to sell him out.
