I mean not really the downfall. The half-brother still got the company and able to save his mother face I guess. But kind of implied in novel that he has a bad reputation for stabbing his brother behind his back. And he now has to work for those relatives he hated instead of MC. And he never gets his happy ending despite getting the company, cuz he only love MC but he never stands a chance. . The whole car accident fiasco left the mistress and the father continuously fighting too. MC still talks to the father. And MC is finally free from having to look after everyone as an eldest grand-child. And by the end to the extra, he live a happy life with ML.
I really wanna see mc's father, bitch mistress and ra*ist brother downfall. please can anyone spoil me?
