No I totally get it why people drop this manga, and for good reason.
For one, the manga had a pretty family friendly setting, nothing was overly fucked up even through the initial abuse the MC suffered.
The MC is not stupid, does not fall for any traps, everyone is always open to dialogue and to solve things talking without acting. They are overly mature and everything gets resolved quite easily and fast, the lessons are learned almost immediately which, for teenagers this is a literal impossibility lol
Then comes the extortion of Hanabi. I feel like the author tried too hard to have someone get some leverage on Hanabi to keep her on a leash and pay back the bullying she caused, but a video in which he's just... crying and mocking him? Can't even remember if it was because he wets his pants as a child, but THAT's his blackmail material???? THAT is why she agrees to prostitute herself for??? It's fucking ridiculous!! It's too much of a stretch!! It feels like trying too hard to add edge to a manga that never had any and has been quite wholesome for quite a while for no particular reason, and as a very badly implemented ploy to force us to feel pity for Hanabi when she deserved none. What's so bad about making someone irredeemable? And why put her through all that if she was not planned to be irredeemable, then?
I wouldn't be surprised if this shit gets axed. The author fumbled really badly on this.
