I just started reading the sweetest man (aka Dalkomhan Namja) and I'm obsessed with the relationship between the super Alpha dad and the friend who is super unfazed by what the dad does. The dad is so used to using his 'domination' and having everyone bend to his will, and the friend is super matter-of-fact and stoic and doesn't take bs.
(I don't know if this helps at all but heres an example)

I don't know if I'm using the right wording or explaining this well.
But I would like to find more couples like this if you can 😁
