So he stays awake when he fights and kills? Is that the reason why he feels bothered by the monsters fleeing?

I think it's pretty obvious that he sucks life force. If he doesn't have enough he falls asleep. So he likes killing and needs to but because the monsters run it makes it difficult and he has to get the source of medicine from somewhere else. But that's just if the story is as cliche as I think it will be. This will prob result in a moral conflict between the mc and ml.
How this will go on. I've read the raws and I actually feel like yiyoung.. I don't fucking know what director Kang will do. Was it a one night stand? Or would he like to date yiyoung?? I mean he keeps being nice even after they had sex.. he is such an gentleman and into some kinky stuff bruv, I love him xD
Also I love how yiyoung is trying to be professional after ALL THAT
