I mean let's be fair here. Everything that we've seen his sister actually say has been pretty good advice. And his sister never forced him to do anything, just advised him on what to do. He chooses to follow her advice since it always works out.
So like him applying his sister's advice to sleeping with this random dude isn't the fault of her. It's more just a testament to his stupidity and naivety. Like bruh what normal person would hear the advice of if you're going to help someone, you need to take responsibility and help them to the end and go oh so that means that I should continuously sleep with my rapist? to "help" him. Like no mc just dumb af.

i think that person might be what we call a child. mc narrated from the very first panel that eversince he was little, it was already like that. are all kids smart enough to make decisions all by themselves? no. that's why his sister who is a lot older than him was the one who told him what to do and what to choose. but thing is she never really guided him properly that she made him too dependent of her "advice" without even talking it out or explaining it to him. but now that i've realized it, yeah. it wasn't her fault he ended up being like that, but the parents' (:
I understand that he may have been super dependent on his sister. But still, I feel like it's so strange that as a high school student she's the only person he's ever learned from. Like I didn't learn much from my parents either but there are things you obviously learn from friends and the internet and media and just with your common sense. I guess it doesn't make sense to me how he was still so childlike. And I guess rather than me seeing it as his sister's fault, I feel that it's probably something more to do with his personality.
funny how almost everyone in here overlooked the part that his sister literally ruled over his will without even talking things out. if that's a normal sister, she should've noticed how he ALWAYS goes along to what she says and explain things way better. his judgement on his first meeting with Aya was greatly affected by his understanding of what his sister taught him.
