The MC was the only person who wasn't rejected by the ML's soul.

It was also mentioned that the system and the main system also tried to use other hosts to try and 'woo' the ML by becoming the 'slag' shou but failing since the ML will always kill the other host's character.

Only the MC was the exception. The ML always falls for the MC. *laughs*

The reason why the ML has to be hurt and experience pain is because he's currently a criminal.

He's being punished by the system's organization.

The MC hurts the ML by becoming the slag shou = ML being in pain = Increase in completion rate of the MC (the more points he gathers, the sooner he can buy the medicine to resurrect back into his world) + The ML receives his 'punishment'

So this is a win-win for the system and the MC

The reason why the ML was serving his sentence was explained in the end.

The crown prince of the ML's world tried to make a move on the ML's older sister. (Like the evil move. The Crown Prince planned to force the older sister of the ML into doing *that*)

The ML beat the crap out of the Crown Prince but the Crown Prince is still the Prince so the ML was punished.

He was punished by letting his soul experience pain via MC's mission.

After going back to his own world, the MC wakes up and doesn't remember anything. It was explained that this is to protect the well being of the host.

6 or 7 years has passed since then so the MC is no longer 20 years old. He's about 26 or 27 now and he's trying to do his best into blending in back to his world. Since he just woke up after a 6 or 7 year coma.

The MC realizes that something is missing and that he knows certain things that cannot be explained. Like: How the new ancient drama about Kings is wrong since the details don't match. (Since he has already experienced this first hand in the other world)

So another thing is that, when the MC first woke up, somewhere far away, a man wakes up and is found by a farmer.

The man asks: "where is this place?"

And the farmer answers and says some words.

The man sighs in relief that 'at least it's the same language.'

IT'S THE ML! *celebrates*

what makes me happy is that (in my own understanding. *The translation of Google-sama is somehow difficult to understand* But, the ML travelled through space and time and chose to permanently live in the MC's world.

It's very different from the other novels.

So, the ML tries to track the MC and finally finds him.

He introduces himself as the MC's boyfriend and the MC is skeptical at first since he can't remember anything.

Then after spending time with the ML, the MC can't remember him but his soul and body does. (So at least the MC is reassured that he knows the ML)

At the last chapter, the MC finally remembers everything.

The ML is very happy about this since he was also prepared to spend the rest of his life with the MC with or without him remembering his memories.

So now that the MC remembered everything, the ML feels overjoyed.

And they confirm their love for each other once more.

I think that there's also a subtle second ship. That's the ('System' of the MC and the 'Main System.')

It was shown that the Main system thinks that the code of the system of the MC is 'cute'

from his singing competition all excited because the main system told him that the MC was right on track, only to appear right as the ML and MC are about to f*ck HAHAHAHA.

For instance, in the "entertainment" arc, he starts off extremely possessive/controlling of the MC, including having the other followed/watched. However, by the end, after a (admittedly handwave-y) series of psychiatrist visits, he actually outright states that his previous actions were wrong and wasn't representative of actual love -- that people in love value and respect their lovers boundaries, which he had not done up to that point. This is legitimate, deliberate framing from the author!

OK, so there's a vaguely minor exception in the emperor/prince regent arc, where there's no deliberate consent obtained, and the MC actually isn't sure if he's in love with the ML even by the end, unlike previous arcs, but it's a small blip in the grand scheme of things.

He started off in the first & second world, hell-bound to complete his missions (even though he couldn't bring himself to be scummy and fails ultimately). But by the 5th-6th world, he has accepted his inability to intentionally harm the ML because of how much he loves him and is willing to deviate from his missions just to be together with his partner.

during his emotional struggles where he was torn between completing the mission for his life, his own moral views and his attraction for the ML. Especially when he wasn't aware that it was the same ML. But, then again as was mentioned by the main system, that was the price he had to pay for being kept alive despite the fact that he should have died.

World 1: Ceo x"adopted son"

Seeing Li Yihan’s appearance now, Chi Zhao almost stopped breathing.

Too... too handsome!

Such a handsome man, the original owner can still go against him? What a nuisance! Qi Yuan’s conscience is too badly damaged! Bad eyesight!

[Though our MC is not yet bend here but I think he's already hooked haha]

World 2

Interstellar Military Marshal

ML to MC 🤧“I will treat you really, really well.”

So well that you will fall in love with me completely.[Screaaamssss acccck so sweet]

Until you can no longer leave me.

And eventually become someone who well and truly belongs to me.

Our MC thinking about love:

Chi Zhao knew himself best. Although people may think he’s exaggerating, he is actually very devoted. Once he likes something or someone, if his life permits, he could probably continue to like it for several hundreds of years.

World 3

Entertainment Bossx artist

So yeah our ML have some thinking about leaning to the yandere side but his rational thinking still won for his love:

"But the fact is that it was abnormal. It was just a morbid and paranoid disregard of the wishes of others. He selfishly concealed the truth. In this relationship that was never clear and unclear. In a position comparable to himself, he advertised this degeneration of possessiveness as love. If this is love, then love is too terrible."

World 4

Emperor x regent

Our MC and d system interactions are really cute hahhaha there is also the Main System: systems watching MC's world be like this:

"He likes watching the drama of the overbearing wife whipping the loyal dog husband, hahahaha"

World 5

S's Entinel x guide

ML waited for MC for 5 yrs;_;

"Shen Wumian (ML) felt that he should get used to it, but at this time a heart that was already riddled with holes was still bloodied by Chen Yi. (MC)

ML to those who wants him to marry/see other person:

"Sorry, I love my partner very much and will not betray him."

ML to get back MC hahaha:

"What's the use of having a face in front of my wife?"

ML fighting the supposed natural instincts, he love is greater than just lust yeahhhhh:

"The sentinel's instincts were clamoring all the time, urging him to occupy, plunder, and persecute him, but Leo didn't want a partner who hated him, what he wanted was that his partner loved him wholeheartedly."

"He wanted to take back a reciprocal love."[this!!! Yes this is it !!!]

World 6

Ceo/mafia?

This Time the story MC adopted many children, one of them is the ML hahaha

World 7

Cultivation

World 8

Real world

The system/s operate a virtual world and other world can have a contract with it. ML was a prisoner in his world why??his country crown prince wants to have his hands on his sister[it' implied that d douchebag prince reall wants to tarnish his sister aka/*ape.

Though his sister was saved by his Brother-in-law/his sister husband. Our ML already hit the crown prince haha and it was shown publicly the video so even the higherups wants to let go, they need to give the ML some punishments.
