Sooooo the beginning of this relationship is pretty effed. Alpha section chief tries to slip an aphrodisiac potion to his subuordinate, an omega. The potion will induce a heat where the omega is desperate for the alpha who mixed his blood in. A drab and boring beta ends up drinking it by accident except surprise! He's actually an omega. Boning happens, feelings happen, and the alpha ends up realizing he did an absolutely horrible thing but it's really glossed over for a quick resolution. Kind of a shame about the story because the art is great and the characters are all adorable.
