Why did Jay's mood just change like that??? Sus

Right?? About the i love you part i think it's probably bc in order to yoon taste better he has to be "happy", did you notice the black clouds(?) around him in this chapter? I think that's what it was about

That kinda makes sense but It was just to sudden. If it's just about making yoon taste better he could have been nice to yoon from the start? I'm down for the smut, it just doesn't make sense to me situationally from the dark mood of the last chapter.
