Best part of the story is the dynamic between the witch of the end and the FMC. The witch is the ascended version of the FMC in the far flung future. Due to timey wimey nonsense the MC’s actions ripple to the future allowing his actions to change both his relationship with the FMC and the witch. But the two versions of FMC f*cking hate each other and are unwilling to share the MC. And this isn’t like petty jealousy these mfs are fuming, fighting and scheming over the fact that the MC might like a different version of them. It might be the craziest bit*h behavior I’ve seen in a Yandere story. Fighting yourself is such a peak Yandere concept that reading this made me want more dynamics like it.

The story starts to fall apart after Lynn's (MC) realization that the artifact Yveste (Villanous Princess) is trying to contain is actually a rank 0 artifact (potentially world-ending and highly dangerous). Before, the author would've written a clever solution to the seemingly unsolvable problem, but it seems like the author wrote himself into a corner with this one because the solution Lynn comes up with is so s*upid.

Lynn decides the best way to deal with the archdemon sealed inside the rank 0 artifact is to trap it inside his own body, then summons another archdemon so they can fight each other inside his body. While they are fighting in his body, the author emphasizes how much grueling and ungodly pain Lynn is in right now. The second part of his plan is to use a skill he has that stores pains he's experienced and reflects it at his opponent at 2x the power at the 2 demons. Which are currently in his mind. Let me say that again. He uses the pain reflection skill on enemies that are inside of him.

In this novel, these 2 archdemons are considered mid/low-tier gods that are beyond mortal comprehension, albeit both are in a weakened state. Lynns knows his pain reflection skill won't be as effective on them. So before the fight, Lynn decides to sit on a chair that causes pain so intense it mind-breaks normal people in 3 seconds to store up as much pain as possible for the skill. While in the chair, he experiences the equivalent of 1, 000 deaths.

Mind you, he is doing all this while being essentially a regular guy. No pain tolerance skill, no mind reinforcement skill, no nothing. It's just pure willpower and plot armor. In the story, he is considered the weakest of the weak, relying on his quick wit to outsmart his opponents. I could've maybe let this entire plan slide, if only the story properly built up to it, with Lynn building up his pain tolerance over the course of the story leading up to this moment, but it didn't. The only other time Lynn experienced pain was when he was getting beat up by Rhine in chapter 5. Going from an interrogation beat-down to gods ripping your body apart with no in-between is so absurd. It's like going from fighting a coughing baby to fighting the sun.

I normally hate yandere types, especially when the author has multiple and they fight over an oblivious protagonist, but at least at the beginning while the dynamic between the princess and MC wasn't healthy it felt fresh and interesting.

I liked their relationship when he actively gave up his chance to run away to help her, and I think the story was at its best when he saved her. The book did a really good job of setting her up to be a villain character, yet gives her a sympathetic background and writes in a way that still keeps her within the range of a likeable character.

With this all being said, I think the book went downhill from here... Their relationship was instantly reset with the witch locking his memories but I continued thinking it was a necessary step towards her seeing him as an actual person.

Then it starts going into the past and future self of the princess starting to fight over him. It started to go down the path that I always hate, but it still felt different with the dynamic of them being the same person but its still just feels annoying that the build up from the first Arc just evaporated into a cat fight where the poor male lead is stuck in the middle.

While all of that is going on, the author has started going down the Harem route which I'm just really tired of. The witch commands him to gain the trust of the 4 original heroines and plant a mind control thing, so he started to seduce one of them. Its probably just because of how tired I am of worthless harems that never go anywhere because its so rare for a story to actually progress past the beginning phase of a harem but its just so annoying that its going down this route. It's then further amplified by the inherent disgust that comes with the ML seducing the girl by tricking and deceiving her while being incredibly manipulative.

Then on top of all of this the author is adding so many weird fetish things into this... There was already the weird dynamic with the ML and the princess but there is just so many things... The book is setting it up where his sister will most likely be in love with him, and whenever she gets excited thinking about him she pees herself. All of these little weird fetish things added for seemingly no reason is just one more thing I dislike.

Overall the story isn't bad but its just gone in a direction that I really don't like. I'm sure that if these things don't bother you then its probably an enjoyable read but for me I think I'm just really tired of harem, and I've always disliked yandere so I think the book is just not for me.

she starts competing with herself from the future

specifically the future one in which he's supposed to seduce then mind control the female leads from the main book. Don't get me wrong I know there's a reason for it and stuff but still changing his memories so that he's more devoted to you is just f*cked up. I accepted it at first because it did actually help him escape her being overprotective but still.

his memory lock was disappointing and while I did really like the idea of a yandere being posessive/fighting over herself, the future one does next to nothing with the advantage she bought herself, only getting cucked by herself as if she doesn't herself enough to know how she'd act. Shes also just a non character in general, much more than earlier.

her trial of cucking the hero was a s*upid story decision. Not only is it tragic to read, as a short term goal its too far fetched to keep things interesting. Theres a lot of characters and plot threads being sidelined so the story can play out a classic "save the girl while acting cool and make her fall in love" arc, adding another super dependent and devoted character while the MC can't handle the first 1 (2).

the MC has also just been getting into deeper and deeper sh*t back to back for way too many chapters with no break. I really cant see how he gets out off his current meta situation without an asspull.

his durability is practically infinite. He can tank literally anything as the plot requires. He'll always be at the verge of death holding on through sheer willpower fighting against beings that are supposed to have an immeasurable power gap as if his body has no actual limit as long as he can take the pain (he always can, and always maintains high level cognition through it).

also some of the plot changes with the 100k years future feel like they're there because of convenience. I'm not sure if the author can manage to explain it in a way that isn't just a happy plot hole.

The progression in how an original heroine also fell in love with the MC (through countless deceptions and some genuine feelings) is also done well

• She ties a shackle around his neck and connected to her wrist. Fyi, when she did this she was is a very weak state physically and also paralyzed, while the MC was is a very strong state. So you may be wandering how did she manage this in the first place? Well if we go back to my previous point about the MC, he becomes pathetic and s*upid when he is around her, that's why.

They spend four days like that, stuck together.

• After the fourth day, something happened that made her mad and she tied him up on the bed, each of his limbs tied to each corner of the bed. Naked. Mouth and eyes covered. Fyi again, she was still very weak and still paralyzed yet she somehow did it.

He spent a week like that, she fed him mouth to mouth, and he probably sh*t and pissed himself.

• A bit after that she places a mark on him that, to my understanding, is basically and aphrodisiac that makes him lust after her in certain moments

He made a move on her, and she refused. It was her way of training him or something, and instead she allowed him to fap himself over her leg, which he did
