Bruv I can't believe I'm getting more stressed about reading this than my examinations.. The story is definitely a messy, complicated, and controversial thing between us people who are more used to only having 1 lover (+ becus it is the normalized thing in our world).
I feel like the blonde dude doesn't really have feelings like "love" love to the husband and I just genuinely feel bad + hating badly on the wife's decision (It's quite a... Questionable thing to do and a brave one too).
The Husband, I just don't like him for some reason not because he's gay (idgaf about that) but because HE FUCKING CHEATED BRO, FUCKED IT UP WITH SOME BLONDE DUDE. And we're supposed to feel bad? Hell nah, he messed it up but ofc blondie had to swoop in too.
I definitely have a lot of emotions to feel about this and mix emotions, but one thing we can all agree on is that Yuki's parents suck as fuck.
