He doesn't let them treat him like shit because of his brother. He is scared of being a nuisance to other people. Didn't you see the part where he said he worked hard to try not to be a disturbance to his parents?
I did. I also saw where he blamed his brother for his parent's divorce and told his brother that he didn't want to be like him as if that was an explanation for not standing up for himself. He has a lot of growing up to do and I'm no longer sure if I want to stick around for the journey. Sorry ╮(￣▽￣)╭
You're very much welcome to drop this manhua if it does nothing but frustrate you. :)
Exaclty lol
But I honestly just find Yohan frustrating and annoying at this point. Like, he lets people treat him like shit because he blames his brother's actions for his parents divorce?? As if they were happily married before then? Like, I know I'm supposed to be sympathizing with him, but maybe I'm just too old for this. I only started this manga for the smut and sex buddies to lovers shit and I'm not getting it (╯°Д °)╯╧╧
