Feels like the kind of story that could potentially be great with a lot of chapters, like get the bad shit over with at thr start and start seeing growth and happiness. Right now, though, it's just 2 chapters, ao it's only the bad shit. Not gonna be received that well yet.
It's not fun reading someone go through this and only a psycho would really enjoy it, but honestly it does fit thematically. She used someone all his life for her pleasure and ego, and now she is being used. Half of this manga does seem to be about punishment after all, seems similar to me as...
Basically, don't be a tsundere. I don't blame him. She think she's cute saying all this negative stuff about her brother as a shield because she doesn't want to reveal her true feelings, but people took that and ran with it, destroying him. Even here, she couldn't help but comment on how...
Why wouldn't he be angry? They're still trying to use him while acting like they're not. And he got a sliver of hope thanks to literally the only girl that never treated him that way that maybe they wouldn't either, just to be reminded of these hoes being hoes.
Dude, she is actively telling you she see you differently from the rest, that she WOULD respond yes to you. Take the fucking hint already and put a ring on it!
But seriously, why did she had to say just kidding?
Just saying... Kotono loved our MC first way before anyone else. She was willing to get with him even when they both thought they were blood siblings. I know who I'm rooting for.
