The villain is like the MC of Re:Zero that constantly dies (for very weird reasons) and reborn. To make him worst and unsympathetic, the story just added that he is a prisoner and that he dies from random stuff when he harm someone. I say "the story just added" as there were no build up or further explanation as to why he was a prisoner and why he was harming others beside the hint that he is crazy. While it may be as what is state, the mere fact we can assume otherwise doesn't sit well for me.

In one of the reborn life, he survived from his lover saving him. His lover died from her hidden disease, he tried to save her by researching on the cure but failed and now on the mission to revive her instead. In the end, he found out a technique of reviving a dead person by sacrificing MC as the most compatible life to exchange.

First off, see how for plot convinience it needs to be MC in this world of 8 billion people.

Sound tragic right? Well to make it less tragic the story flip it last minute and change to how in fact the villain actually just love himself so much and find her as the antidote to him not dying... If you go back, you can see the real reason he kept dying is because he's doing bad deeds. This is a HIGH IQ VILLAIN. Let's assume he never notice the correlation, but he never tested if being lovers with someone else could help?

I also need to point out that in raising kids, punising a kid WITHOUT telling them what's wrong is just not the best way to teach someone, we learned this in this kind of times, you telling me the future times forgot this or is the future agreeing punishment without being clear of the reason is okay.

It just has so many holes. And the ironic part for me is that we get to see MC buying the cure for the disease in the system AND rewriting the timeline to one where MC won and is alive.

Oh the reason why villain can't but the medicine? Because the system can't provide discount like the system offered to MC because well... reasons. And system sacrificing their life for MC.

Entirely going around villain point as to why there are people who have good fate and some who have it bad. And the entire answer of MC of experiencing what it feels like to die and live again and again doesn't really work when the villain is doing that?

And also:

Villain: continuesly die for random reason and so biggest fear is dying

MC: and you said you love your lover

??? I was laughing so hard when the author correlate fear of death to mean he is narcistic and never love his lover. Like what, author needs to touch grass.

like how the antagonist was revealed to be not smart at all and was just over using the learning system to gain the "main character halo" which he envies is innate from MC (very YA with the MC being different from everyone else and is dependent on your preference if you can enjoy the work or not).

Also, the antagonist is not at all crazy, he is a psycho or narc but not crazy at all and knows what he is doing. He is only clinging into the supposed "lover" because she is a trophy that serves as either his proof that he can still live because she basically stopped the cycle of his deaths or his justification which doesn't really matter as long as it/she exists (like how serial killers usually have a "great family" as a façade). He just became crazy because of the revenge from the learning system (which is why even the MC is surprised that he became crazy when she just did such a basic revenge of mental torment through nightmares).

The medicine thing is also not a flaw because the antagonist can indeed buy the medicine only if he is indeed working hard to get it, which he is not. Also, the learning system unbinds from the host anytime there is an immoral act (ex. Killing). Added with how the antagonist is basically speedrunning the rebirths, he won't be able to accumulate the points nor will he be at the state of "point poverty" that the system will give him benefits (since he's smart enough to not waste points nor be at a lack of it). Also, it's sus how the antagonist's "lover" became in that state when it was also mentioned in the work that the generative disease was discovered after the antagonist's clinical trials (unless I didn't understand that part properly lol).

Oh and yeah the relationship between MC and the system is not that of a host and a system but rather of an admin and a system so tbh it makes sense why the system was buttering up the MC since she's essentially it's boss and can basically decide if the system will be destroyed or not.

What's weird is the use of the system to remove a minor villain not related to the mystics of the story world at all when the families or even the ML can deal with the guy instead. Overkill tbh

MC had to learn how to hack and had to learn it a lot but still only knows the basics that she had to bluff her tech employees who are slacking. Also, ML is only knowledgeable enough in tech and code because of the nature of his father's company but is still not the typical *types random stuff* "I'm in"

such as who the grandfather from mc's father's side is and why he is helping the MC when he us from the higher/alternate plane with the author basically rounding it off as because MC is MC LMAO

but ML basically is the greenest flag and shown a million aura points with the ending cause damn he basically destroyed the antagonists in their prime without having a golden finger at all (since MC prevented the rise of these antagonists but ML faced them off squarely)
