Will anyone hear me out if I say Kwon Hyuk is Joowon's (albeit not actually evil) version of Kang Jinmook.
Hyuk heavily undermines his own abilities and lets himself appear as innocent, specifically under hkh. If you look closely, you can see he's actually quite cunning and purposely puts on this almost naive front. Just like kjm does to hide his true nature.
Furthermore, kjm takes care of Dongsik's mother where Dongsik couldn’t, to the point she recognizes kjm better, as if taking Dongsik's place as "the better son". Meanwhile Hyuk inserts himself into the Han family and plays to every string of hkh and replaces Joowon as "the better son".
It's such a shame to me that Hyuk is such an underrated character because I truly think if you look closer, he's a lot more complex than you'd initially give him credit for. And I love analysing him so much
