Hopelessly Devoted

Yuuji isn't your usual Buddhist priest - he's young, good-looking, and his natural charm makes him a hit with everyone in the shopping district! Unfortunately for his leagues of adoring admirers, though, he says he's all but sworn off love, dating, and marriage, and that his life is devoted to the practice of his faith. There's just one thing he isn't telling anyone: Yuuji does have someone he loves, but they can never date or marry - his childhood friend, Saburou!
