minor spoiler
his death [in the novel] is also a yesn't state, but him dying is honestly the best outcome as a penance for what he's done (and also romance just doesnt suit MC)
also
the baiting admittedly does get super annoying, so this story might end up with only plot-focused readers sticking through to the end.

waw this might be the most yesnt manhwa I've read so far, from comments here and other sites, this thing somehow sparked debates LMAO. And I agree in all points! Jesus have this manhwa struck so many red flag points for me, since I'm usually so picky and easy to irritate when flag points like pedophilia, harem, or romance between lead characters happen (I like action no romance no harem), and female character sexualization happens.
But so far, here's some stuff you can know now if you're like me, and is wondering if you wanna continue;
1. Yes the female characters have big boobs. The art is nice, and almost every female character has big boobs, even the students, and the ones with small boobs are borderline loli baiting atp. It's irritating, but they don't pay special attention to it and doesn't really go for panels that concentrate on their boobs or show their lower parts, if that makes sense. Like, yes they're just like that and no one gives a shit so I can appreciate that.
2. Is there pedophilia? No, but I'm seeing a flag. Spoiler, the mc's ex also got transmigrated in the game, and got transported into a kid's body. From my research, despite the mc having lingering feelings for his ex (this has always been the case since ch1 even before transmigration), he does not pursue it in this world and actually rejects her.
3. Is this a harem? No. Yes there a lot of female characters that will like him in the long run, but he will not accept them because he's not over his ex, and because he's too busy with surviving. Atp I think this guy just really regrets being a bum in his previous life and can't accept love.
4. Will one of the students have feelings for him? I don't think it's anything that deep, from what I've seen and from what I've read, I believe it's more on the, "this person is really amazing" level type of admiration, but if I find anything that develops more into the love zone I'll update because I hate that too. But from my research, spoiler, it looks like they're actually only headed to uncovering the details of what happened to mc and his student's parents, it actually gets dark. There are levels of betrayal in here.
Spoiler, so is it harem or not and what will be the end game? It's not technically a harem because the mc doesn't engage with any of the female characters' feelings, and I can't call it goon slop because all story lines were actually written quite well, despite it looking man centered, there's actually a lot of details in each characters story outside of mc, he just affects it because his character, in the first place, have always been a perpetrator or related to a lot of shit, and he's there to alter it. But the female characters doesn't lack depth like most harem or romance manwahs do, they actually have lives of their own and aspirations outside of him.
How about story wise? Honestly, story line, characterization, dynamics, world building, and even magic structures are pretty damn solid. There's a large variety of characters here and they don't lack much despite it being an adaptation (usually manhwas have a hard time giving much depth cause of how time and effort consuming they are to make, but this is pretty solid). Also, it might just be me, but the harem and romance flags, despite peeking from time to time, actually isn't there?? If that makes sense. Like he's so dead to everything and the story pacing is well made that it doesn't feel that way, the peeking is mostly there because you're expecting it to happen, but it doesn't. It's just so nonchalant LMAO.
The ending? MAJOR SPOILER, it's marked as tragedy because he dies. As established before, there's only ONE timeline or route where he survives, and unfortunately, he didn't pick the right actions. I don't know what conditions happened for this to happen, but that's basically our ending.
Anyways, try it out if you want. It's pretty good, just kinda sus. Like I feel like I'm playing a game of imposter or something lmaoo. Will update if any of those flags actually do come true.
