I don’t think the author thought ahead when starting the story, most japanese bls run very short and they are not intended to be particularly good stories. I’d like to think that had they known that the manga would get this much attraction and run for this long, the story would have begun much more differently. And yes, he does apologize. I don’t think I would like the story as much if I read it for the first time now in my age though lol nostalgia is a big factor for me
I also think she was too young like us, and that we kinda grew up together. Both the author and the readers had the opportunity to experience different things and learn more about the world in the meantime.
It's speculated that she was around 20 when she started this in 2006-2007. It was a different world back then, too, and she followed the trends that were current at the time, according to what was politically "correct" back then, too. I think it's actually refreshing to see her changing and improving and making this show through her characters as well making them more mature as she gains experience in life as well.

how is this rated so high i can't even get pass the first vol. why is everyone coercing him into havung sex and blaming him for it. and why does he APOLOGIZE FOR IT EVERY TIME WHEN HES THE VICTIM
