why are those family reunions/events so relatable? is it because it's an asian family? or are there other places in the world that have like asshole relatives as well?

I'd guess there is universality in there. Groups -including family - have built in need for conformity. If you're not "inside" (conform like every one else) you're "outside, and the tribe will protect against "outsiders", either by trying to bend you, or by casting you out. Gossips and hierarchy are built in too
It has nothing to do with being asian ^^) (there are quite a few movies about family diners, from different country i can think of too :)

From what i recall in past comments
the reason why it seemed to be in a rush, wasn't able to tackle other things being hinted on and questions unanswered.
was because the creator had to stop it since in the webcomic's original site i guess it was either a few were reading and/or buying the chapters which is what the creator need and i guess others were reading them in these sites.
SORRY i didn't want to make anyone feel bad or say i'm a hypocrite since i also read here. Only trying to post what i think was the reason why it seemed too rushed since a lot of people keep saying it.)

People Questioning why....
I guess you'd be able to beat up your crush when you've been friends first and your friendship was that strong wew
or that he really liked seungtaek so much and got really hurt cause he was being this "prince charming" to someone else and Kyubin wants some attention from him (via using MC to hint to Seungtaek that liking a guy is okay but in a terrible presentation ex gay porn and making MC dress as a girl etc.) but only gets beaten up
or maybe it's also cause there was an spectators. the people didn't know that those two are close so he gave a show hahaha
and just like what someone else commented before me Kyubin didn't want Seuntaek's spotless recored be tarnished since he was the first to punch so kyubin told the prof that they weren't fighting, HE was beating him up (the hint for the love and care there is mighty strong)
