Taejoo and Yeongbeom are so similar, these two issues are basically the same. They’re both aggressively righteous…
exactly! given cha si yeong's character, i think this is only the end he deserves - no friends or family by his side. it would've been unrealistic if he admitted his faults at the end
he wants to be a good father symbol to his nephew, and even though he know he should admit his mistakes done in the past, "looking righteous" is already ingrained in him that he can't admit his mistakes in the end
he wants kang tae joo to be his friend as he knows he can rely on him no matter what. but he also knows that kang tae joo wont sit still when he takes advantage of the weak, which he does to keep his name clean and good-smelling to his father, hence they cant be friends.
just want to protect her son, even if it's lying to him. and maybe because since she thought kang tae joo left her, and her son doesn't know that kang tae joo is his uncle, so it will hurt her son less
