It’s a bl manga and an omegaverse where the uke is a beta but pretends to be an omega bc he’s in love with his childhood friend (an alpha) and he gets into a relationship with him (still pretending to be an omega). The alpha even marks him and all and he wears some kind of band on his neck to protect his name from being bitten. There was also a part where he goes into a “heat” but in reality, it was just him putting some kind of gel in his hole and spraying a pheromone perfume on himself.
Additional info:
I think there was some kind of criminal on the loose where he targets omegas and bite their napes to mark them and the uke’s alpha worries about him because he might be targeted.
