From Must Be Endless:

While holding a deep loneliness in his heart that he refuses to acknowledge, Yoshiki cares for his younger brother with the fiercest tenacity. At the same time, he sells his body to men, and despite the ridicule, he relies on their need daily. Amidst this lifestyle, he runs into a handsome younger man named Katou and begins to rely on him, while being manipulated as well. Yoshiki’s little brother, Naoto, and his classmate Shuu’s life-sized love story is featured as well. With a powerful, deep flavor, this is Kimura Hidesato’s World Compilation!
