ML sees a stranger in his house and instead of calling the f*ckin goddamn police or bodyguard or even fight him on his own- he took MC upstairs to have s*x with him? LOL like what???? there's no "hello" or "who are you?" or even "why are you naked in my house?", he literally sees MC and goes in lust? excuse me sir. And what's even more bizzare is THE NEXT DAY PART??? suddenly the ML knows the mc's name?? and told the kid (his nephew) not to disturb the mc's sleep??? Did they talk during sex??? what's going on? the author didn't even give a tiny peek at what happened after the ML took MC to f*ck.

oh and also, the MC apparently went to sleep with a kid, naked. Like full body naked while holding the kid. I know there's nothing pe*verted about that since none of them are thinking of it as anything beyond sleeping, but the house has maids, yeah? and none of them raise a brow at that? Because if I were working in someone else' house that has a kid in it and a stranger got invited by this KID and they proceed to fall asleep naked, the first thing I would have done is to call a COPS.

Even parents rarely ever sleep with their kids naked, and you telling me a stranger sleeping with a kid naked is ok???????????? HEHE.

The ml, as the kid's uncle, should have done more than f*ckIN TAKIN THE NAKED MC TO HIS BED goddamnit.

(And the MC isn't actually sick like the story suggests, or at least in the first arc. The og he took over is described to have rabies but truthfully, people only see him as someone with rabies bc of his barbaric and rude attitude towards the people that disgust him.)

In the first arc, our MC was not even with any sickness, the original just had a hot temper (I usually liked the original owner way more than this MC), and this was completely justify with the context. Then, one day, he just saves a 5 years old kid from kidnapping. Until this point, it was alright, BUT we suddenly discover that it was the kid's birthday and the MC takes the kid away (just because) and later comes to the kid's home and sleeps there (and NO ONE STOPPED this completely STRANGE at all ???? - 0 common sense). But, if you think this is already an unacceptable bunch of nonsense, things get worse when, in the middle of the night, the MC goes to the kitchen NAKED (in a house with a 5 years old kid) because "he doesn't care about what others think about him", but he's just being an jerk. And he founds this ML that, just looking at a NAKED TEENAGER, gets hard and they f*ck. Hahahahahahahah (this is a disappointed laugh, ok?). Then we have tons of nonsense and they both having s*x. What will also disgust you is that, after all this, the MC returns the body to the original owner (after doing whatever he wanted)

The system says that our MC has to "cure" the original owners to succeed, which is quite disrespectful in the way it is put here. And all the characters are so disrespectful with the original owners issues, SPECIALLY the ML (he FORCES the MC so he can "recover") apparently he knows how to "cure" autism after reading some books (and let's agree that the original owner wasn't an autistic person). Even if the ML sees how "uncomfortable" the MC (he's pretending), he's forceful because, in his mind, it is this way that he can cure our MC. If a autistic person was in the body, I can't even imagine the consequences of the way he treated the MC. I hate him *argh*

This novel does seem 1v1, but I will note that MC does not stay in each world until death. With the system, MC is only meant to stay until the original fate has been reversed, with his score being docked if he stays longer. When MC leaves, the original soul will take the body back over and continue living the life MC started, with what the MC did seeming to be 'memories' for them. How does this come into play with ML's soul? No idea honestly, not much is known other than it's the same person/soul in each world. I don't know if ML is only temporarily with the MC while the MC is there, but the novel does cover MC 'watching' the ori!MC and ML interact a bit after MC has left - slightly awkwardness has been mentioned as the ori!MC adjusts to suddenly? being in a full-fledged relationship, often with a man he's already slept with. I personally feel a bit weird knowing that my good 1v1 couple suddenly turns into... potential MLxori!soul?? in each world after the MC leaves, especially since there's a pretty clear distinction so far between MC and the souls he takes over for. Once I finish the novel I may know more about the dynamic, but for now, it rubs me a bit... weirdly and I ignore it to the best of my ability.

Rabies in the first arc? Nah, the author writes that the ori!MC acts rabid due to various reasons involving evil family members and calls it rabies. Second arc has "austim"... that the ori!MC?? developed??? and that was cured???? Yeah, no, a better descriptor is that the ori!MC was extremely introverted and isolated, calling it autism and having it be developed (and cured) is pretty laughable. Following that, having (severe) asthma apparently means that you can't drink tea (a quick google will show you that herbal teas have been used to get relief from asthma symptoms for who knows how long. Even more astounding was when it seems like the author wrote that organ donors (not the recipients of the transplant) have to worry about developing rejection after donating... which is when the recipient's immune system doesn't recognize the new organ being part of their body and attack it, in very unprofessional terms. Organ donors literally give that organ away. they don't have to worry about rejection??? Most recently for me, the MC decided to make money by... writing a book about mental illnesses (based off his past experiences with the above problems of 'rabies' (not), 'autism' (not), severe asthma, mysophobia, claustrophobia, as well as extreme fear of loud noises and the color red). The book title mtl'd to "An Overview of Mental Illnesses" and seemed like it aimed to distinguish between various phobias, mental illnesses, diseases, etc. and to help decrease stigma towards such things within the community (which quite, frankly, is laughable coming from a character who's main goal in each world involves solving/curing said problem to the best of his ability and who also frequently dislikes having said problems. He's also made comments about mental illnesses being a matter of having a strong enough will??? This book gets extremely popular, moves everyone, and no one questions the professionalism/authenticity of this book that is published by a high schooler.

The settings first started after MC arrived. The body our MC had occupied had a mother that just died.

We could conclude here, that the original is very spoiled and naive, since he was easily trick and humiliated just like that. But thinking about it. The original just lost his mother and his father immediately brought his mistress to marry. Coupled with his with his identity crisis, the original suffered many mental stress and no one in his family went to comfort him.

Similar to that novel, the MC is considerate to the original person (though he DID it with the ML using the host's body). Also, the world arcs are just projection of real world and will become part of the memory of original person.

Kinda disappointed with the ending of arcs, because they r not well-portrayed (when the MC finished his role, I didn't know what happened to the original owner of d body). - in the 3rd arc, the reason for the endings are told. Also, I don't see variation on arcs so eventually the stories become predictable

Arc1 rabies bitten- he has no illness

Arc2 austistic

Arc3 mentally ret*rded

Arc4 asthma

Arc5 mysophobia

Etc

What I love about the novel is that the story is solved not by MC only but with the people around him, Since the idea is it is a projected world of a real world, every person should have their own participation/role.

Ahaha, btw the MC has another goal, to eat the ML in every arc ?

When the 20 year old teen kill the stepfather who r*ped his mentally ill 15 year old brother, he was going to be executed and gave his heart to the MC who had heart problems. The promise is to look after his brother, that touched me so much

They manage to bring friends and a family member to the system world and continue to live together, I always want to see that ah when MC have more than just ML in his long life
