Heyyyy can someone remind me what the family relations are here?
The two sexy men are Taeju's dads. The blonde woman is the black-haired's mom.
Is the mom and the blonde dad related? They look similar.

Also Euihuyn's dad that just showed up - is that his omega dad? Or is it the same alpha that is also Eiuyoung's dad, but dyed his hair back to black?

I'm confused dude I can quote every romantic interaction these idiots had, but other details just evaporate from my head
