She is only being blamed because 1 he told her that he was in love with her brother 2 she only cares about herself despite the brother always putting her feelings first and 3 the guy clearly doesn't have feelings for her but she still wants him to the point where she proposed just because they are both guys and can't get married
Okay but why didn't he reject the sister?? I saw it as, he wanted to take the opportunity to date her to split the relationship the mc had with his sister since he spent too much time with her which is lowkey fucked. He grinned as the sister watched him give a blow job to the mc, he's not the victim
And the MC saw that the sister saw them sleeping in the same bed cuddling. Ok he could and should have rejected her from the first time he saw her but we know he didn't do it because he wanted to build a bridge between them, the MC always puts his sister as top priority which became a problem for them, the MC couldn't or wouldn't do anything about it so he took advantage of that and did something. But for her to respond that way and called him all types of insulting names knowing full well that she was the one messing with his bf and not the other way around was too much
Why do people feel bad for the bottom?? He literally orchestrated the whole plan to split the brother and sister apart, sure the sister was a selfish bitch, but literally everyone is guilty. only blaming her is crazy imo.
