It's fairly clear it's not disgust even in just the next chapter or so, but the vomiting isn't explained in this season
I don’t think it was disgust. The fandom theory is that he’s obviously not human and his body was rejecting the saliva. And there’s more ever since they started kissing he’s getting human reactions.
There’s more what? But now they’re banging…wouldn’t that mean he would throw up even more? But we don’t see any more scenes of him throwing up…
That’s why I’m saying that making out is slowly turning him into a human. That why he’s adapting more human behaviors. And that’s why he started to get more eager while making out because he started getting urges. Because they made out before his body changed. He got used to it and his body stop rejecting it
Sorry I stopped reading at ch14 when he is vomiting after kiss and seems like was pretending - will it be explained later or not yet and in next season? If not now I’m not sure if I can stomach reading further chapters without knowing what’s going on and thinking he is disgusted with mc
