Be My Love, My Lord (manga)

This is a world where humans keep beasts and beasts obey humans. Born as the second son of a well-known family, the lonely Reiji has always had his beastman servant, Tsubaki, as irreplaceable presence since he was a child.

But one day his feelings turn to love, and Reiji playfully kisses Tsubaki, which invites his bestial lust. His sharp bite overflows with his own repressed feelings, but comes with a dark realization; they are different races, different castes. Can they overcome these hurdles and embrace their love?
