For years mated partners would have to redo their marks almost monthly unless both partners were marked, which was not common practice as it was seen as claming. After some testing and studies were put out it became common practice. Along with feeling a strong bond with your partner, mating dulls down the effects of both heats and ruts, allowing only the other's presence and physical touch to feel satisfied. Katsuki and Kami used this to their advantage platonically mating and spending their time of the month together. But what happens when one of them catches feelings?
