The difference is, Yigeon's brother has been long abusing him, since before Yigeon ever learn to stand for himself. Yigeon can't help but to believe he'll never able to win over his brothee. Meanwhile Taekang didn't plant the same abuse on Yigeon. That's why Yigeon can stand up for himself in front of Taekang but not when with his brother.

I like Yigon standing up for himself, I'm just hoping he'll turn that energy towards his brother.. He met this guy like months ago and he is this pissed but he is still trying to act demure for his brother.. it maddening to see all that grooming working on a guy like Yigon.. he is smart, his grandfather despite all the years Yigon spent giving the impression of no good lowlife, still wants to back him up for the inheritance.. I need Yigon to see his worth, I was hoping Taekang would help with that but despite it all Yigon is planning to go with his brother's plan.. this is giving me a headache.. he isn't even trying to use Taekang to deal with his bro now.. smh..
