The outrage on this thread is funnier than the actual manga.
LOL - you want a dumpster fire - you're missing Konbini Goutou. That makes this manga look like kindergarten scribbling.
The MC isn't any less likeable because he's no longer a NEET Virgin. And Senpai isn't a hussy for taking what she wants. And It happened a year and a half BEFORE current time in the series.
Readers complain about hundreds of chapters of blue-balling like Kanojo Okari yet someone finally DELIVERS THE GOODS inside of fifty chapters (and in a understated artsy - dare I say - tasteful way) and it's worse than Solomon breaking out the longsword next to the bassinet?
Are you really going to crucify a character for what happened in the past? It's not like he was looking to hook up with Senpai when she cornered him at the festival. That's the past. This is good writing, because it's literally the opposite of School Life Shonen escapism full of inaccurate tropes. Human relationships are messy, full stop. And blaming someone for their past without taking into account who they are today is simply being shortsighted.
Seriously people.
tu quoque fallacy just cut that's a worse dumpster doesn't make this one any less of one
He is less likeable because he "loved" Mc never said anything, didn't try hard enough to be her equal, got sad on his own, and then had sex with the first thing to take pity on him. He is pathetic. Senpai is not a hussy she is a bad person she had something go wrong in her life and decided to drag someone else down its literally said that. It's literally my step-dad is a horrible person (who we don't know what he has actually done yet) let's go manipulate a vulnerable stranger.
It's not about "delivering the goods" it's about a step being taken in a relationship and in this case it was delivered between the wrong folks and the "tasteful" is just an overdone cliche.
Would you forgive Hitler if he said sorry? Where do you draw the line? Human relationships are simple, full stop. See the issue with what you said? It's literally just your opinion I have never had a messy relationship and I've had my fair share. Slapping a big fat label on relationships is pretty stupid because each relationship is unique because each person is unique. Is it shortsighted, maybe, is the opposite naive, yes. Are some people really truly redeemable 100% are they all redeemable, absolutely not.
