Koizome Ryu Amegoromo

"From today you are mine. Serve me well." Harunada, the son of the dragon god, visits the youkai brothel Kasumirou, whose workers specialize in taking human shape, looking to hire a prostitute who looks like his mother, hoping to calm his father after the death of his human wife. Harunada himself is not interested in the human concept of "love," however, on his way home he finds a human, Chika, injured in the forest. For some reason, he can't ignore the presence of that human, who hates supernatural beings after a loved one was attacked by youkai. Harunada makes Chika his servant, but... A Japanese-style fantasy BL about a young man with unrequited feelings, and a noble dragon cub who wants to understand love.
