I know it is not entirely the big bro's fault. The evil here are the grandpa who just throw money for child support without checking Dojun's real condition and the uncle who leeching out money from Dojun yet have the audacity to treat him that badly
But, is the bro seriously didn't come to see his lil bro even once? No matter if he's afraid for the grandpa watch over him, he could make some time to see his own living bro. He could see and easily find out how bad Dojun being treated. Living in small apartment while uncle and his family living in mansion. Having too little clothes that he can only wear as much and as little. Being so skinny in that age. Only Jaehee realized it all, because he pay attention to Dojun. It didn't take deep investigation to know how bad Dojun being treated, but the big bro only realized it all now.

I think it's bec a single mistake can ruin his years of hardwork. Just one wrong move and everything he worked desperately hard for might be compromised. The only time he began his move is when the granda weakened. Also I think maybe he thought that since it was the grandpa who was managing the money for Dojun, to give to the uncle, he also checks his condition.

Can't you see how much I and I in his inner thoughts? This asshole just a plain narcissistic. It never occur to his mind that he was responsible of ruinibg someone's life. Even when his heart giving him a guilt, his stubborn arrogance mentality trying hard to deny that. He just thinks he's better that anyone and he deserve the world. Disgusting piece of shits

Well if you don't like him, treat him with basic humanity. Why the need to act all shitty, all the gaslight, make false hope, then run away anyway?
Him being amnesiac isn't an excuse honestly. Because if you at least decent, you won't treated anyone like that. Losing memory doesn't mean forgetting the way to live. He's just that asshole of a character.
Where is the whore of Cirrus's dad misstress? She's running around in the house in her lingerie when it is only Cirrus there, and clothed like refined fake lady when Cirrus dad home. Is she finally get kicked out?
