Yall arent understanding how BDSM sex partners work. They arent dating or together, they only meet up to fullfill their sexual desires. Doms a lot of the time have multiple partners and sometimes subs do too. This isnt a story about a cute love triangle. Im guessing the professer is aware that Eun Woo loves him but he cant give him the happy love story Eun Woo wants so he brings in Hajoon because he has shown to deeply care for him.
Wait, so is this how Hen and Ivan ended up having the one night stand in the beginning. Because they really did hate each other at first, and Ivan accidentally seducing Hen with pheromones?
