The most bad ass bottom I've ever known - Lee Geom.
It's probably just me but based on other omegaverse stories that i've read so far, one can recognize the scent of their mates from other people so i'm surprised alpha can't recognize his omega's scent in beta or maybe it only happens during heat in this particular story
Dou Dong's brother complex is on another level. Poor Cheng Cheng lol
