I think I know why he threw up after that kiss. So hear me out what if it's just a foreign concept to him now and he forgot his past life but his body still remembers acts like this. I'm really excited to see what will happen after they have sex

I think you are partially right but I think maybe for us kissing is "nice" but for him that the concept was alien, he felt a bit disgusted by exchanging saliva and honestly some normal people also sometimes feel like this right? Not to the point of puking lol but maybe it was a shock for him lol he needed time to get used to kissing as an act
Bro your man doesn't even have eyes
