the first concern the protagonist has when getting back to Earth is potential PTSD.

His childhood friend whom he's almost estranged from is exactly the selfish bit*h she seems to be. No "she's tsundere and in love with him" BS.

The people he uses the cheats and gadgets against are not in the wrong. Let us take 2 examples: His first victim, his childhood friend gyaru-chan.

By the original timeline, she was just a regular good-for-nothing gyaru that was involved with some shady f*ckers and ended up being their toy girl. She treated MC badly, read it as coldly, and after she gyaruzied she lost almost all contact with him. So in the end he got nothing to do with her, honestly. What does he do? Puts an alchemical special incubus juiced up slime in her just to make she completely h**ny for him. Why? Nice of you to ask. He does it because. Yes, because. "As she is destined to be f*cked and tossed around, why not me? I am so nice, am I not?" is the overall reason. And a little revenge for her being a d*ck to him. Well shit, this is a little over the top, no? Nah, he got sum f*ck and a nice perfect s*x s*ave that is literally a junkie for his juice (and I mean all his juices, as it is understandable, clearly). How nice would it be if she got the hots for him just for him being a badass, as he was when he defends GF grill in the park? But nah, slime s*x s*ave nicer, yoh.

The second victim is extreme maso womyn. This one is strange. She is a woman that works in an "entertainment" bar. And is one of the most gorgeous women there. Initially, he just gets interested in her because of, well her looks. But then she starts to aggressively insinuate herself to him. He, eventually, accepts. She did so because she has a magic special perception that indicates that the MC will be a good master for her hyper M side, so it is all justified in the end, clearly. But then he remembers that she is an old fling he had before being isekaied, and was such a massive M that he could not satisfy, so they parted ways. Now he opts to get her for real. As she is a religious nut job, he uses this side of her to become even more special. And then we discover that she has a daughter that is dying and he could cure her. What he promptly uses to make her fall more for him. A nice guy, you might say. He saved maso womyn and her daughter. Ah, he tests the cure-all on the other terminal kid, not her daughter, but he dies conveniently, so OK!!!

But my real problem with this novel is the following. He forgot some points of the original timeline. So he has some flashes of things that were bad or nightmares where he says the name of some random grill. And this is sh*t as f*ck. Considering that he had a time skip of 16 years, it is expected that he would have some gaps. But they are especially convenient plot-wise. The gyaru tale he remembers perfectly, his high school girlfriend he remembers fairly well (she abandoned him for some reason that is yet to be told, but he is already planning, or at least thinking of, make her his, not as a girlfriend but more like gyaru, and he debating that "maybe nah" is not proof of shit, this f*cker have a bad rep already). He only remembers M womyn when he sees her tattoo. This one is fine. But then he does not remember why he dislikes some people he ends up coming across or the random woman he calls the name while sleeping. What do I get from that? Any and each of his actions could be justified by his subconscious remembering of what, how and when to resolve the sh*t timeline. This is s*upid at least and takes all the relevance of his action if you think about it. How more drama and urgency would be added to the tale if he got just a glimpse of knowing that something was bad but more nuanced. And then he would solve it somehow. Like some indications, not simple "hey, I got an impression that mom should not come home now, eh" or "this name? Dunno, so strange, teehee". Add that to an unlikeable and unjustified MC, and you get a disappointing tale. This could be nice (and I do not say that as someone that loves revenge tales, believe me, brah). And his powers are interesting but basically take some weight from the plot, considering that he can see when someone lies, dislikes him, or adores him, and so on. This is an interesting concept, but bad for this type of story, plot-wise. It is used as a plot point, like: "oh, mah girlfriend has sum insecurities, how can I resolve that, ah, I wish she would sucky-sucky my peepee already, eh, thinking is hard, yoh".

But I feel that it will end up in disappointment again. And her plot involves the bandit king or some shit, lmao novel, lmao. Oh no, 10 chapters after my review, the Yankee plot got worse. By that read: she was turned into a vampire that is crazy for blood, but only his. And did you not know, vampires are s*x beasts when they sucky-sucky blood, so she is his new f*ck buddy. And in the original timeline, she lost her leg in some motorcycle accident, and they did have a fling or sum shit. But he does not remember and apparently, he turned her into a vampire because he subconsciously perceived that this would be the best course of action (???). So the s*upidity, he doing sh*t and it ending up right, is yet there. Amazing. Oh and from 4 harem members, 2 he gets sexy while using his human masks. Goddamit this novel is more s*upid by the chapter, I tell you.
