i am imagining "this is not how u do it u fing idiot" "tf. this is how u did it mom? She should have left you long ago" "stfu!! you know nothing" "i can see ur skill issues dad" or the father just being disappointed on finding out how his son is a bottom (idk if this has happened or nah in the raws)...and his angered face when he hears his son moans or some type of shit. i think its funny okay-
it wasn't doing too well when people began noticing the decline in art quality, so i doubt it. might be why the ending was so abrupt and didn't cover a lot of loose ends that were addressed in the novel. there might be a small chance of an extra chapter? or at least there's speculation of it, given the ending.
I don't speak Korean fluently, but from what I've read from the raws, he ends up with both. Fucks the boyfriend and gets fucked by the father (not at the same time) and they all coexist that way lmao.
