I think Jaheon just automatically assumed bc of his own past trauma growing up as a luna (omega)
I understand that. And see the point now.
I'm just basing what I saw from chapter 43 - 44, because from what I got from there, past Jaheon seems to have been have been against their relationship (if they had one) from the start.
I also think it was meant to be joke, a bad one, but it was probably supposed to be something light-hearted before the revelation of Jaheon and Muhan's past.
yeah
Why's there a dude assuming that his past self is a predator instead of, idk, some older guy that Lee Muhan was crushing/pining after.
For all we know Jaheon's past self could've ignored his ass (that's why he gets so annoyed and pissed with Muhan) until Muhan turned into his twenties and that's when Jaheon started seeing his "brilliance" and they started noticing each other.
