I want to see the ML abandoning his parents for life and not taking their calls so they can understand how it feels to be ignored from their child. The brother is also petty as hell, he better have a good reason for why he's always trying to take the parents attention away from the ML and not even considering what the ML (his little brother) likes. The brother probably feels like his life is unfair because he is sick so he tries to take revenge on his little brother who is perfectly healthy (and lonely from the lack of attention). The brother is very inconsiderate
The way Jun was thinking Yohan is so lonely and ostracized by his family because he knows how to cook and wash his clothes is sooo funny
I guess being rich means you can't do basic stuff
Truee, jun being so spoiled and can't do anything was often brought up by yohan in the future, including special chapters in here, there was one scene when yohan said "i can't take care of you anymore if i died, so put an insurance on me"
