Every time MC dies for an extended period of time, she returns to her reality. If she dies for a short time, she doesn't go back.

When the Duchess died, she left a will imbued with holy power that stated the duke's family can wish to save Charlotte from death. In this way, no matter how many su*cide attempts MC succeeds at, her brothers can just wait it out, summon her back to health, and get mad at her for dying.

Sounds like hell.

And no, the people around her do not get nicer to her after her attempts. The author has the characters on a loop of "she was adopted into a rich famous family, she has no reason to die".

Which in a way, is a good thing. Because we can truly hate them, and it makes it easier for MC to die.

No one.

Man, I wish one of those brothers did though. Why are they worse than Tia's Men... tsk tsk

Tia escapes to a plague island where the empire ships its sick people to die without infecting the rest of the healthy citizens.

She meant to run away from the Duke's for just a while but became trapped on the island when a plague broke out. As a saintess, Tia spends time healing the inhabitants while trying to clear her mind.

Tia's gay.

What I mean, is, Tia is gay for Charlotte.

Tia and Charlotte are sisters legally. Since MC was adopted into Tia's family.

So while feeling incredibly immoral but unable to hide her growing feelings, Tia ran away for Charlotte's sake.

Every time Charlotte sees Tia, she superimposed the image of the Late Duchess (the only one who gave Charlotte love) onto Tia and gets horribly depressed and seeks death. So Tia thought that by leaving the house, she is saving Charlotte from committing su*cide.

That Sure backfired didn't it? Lol. Tia left for Charlotte, but Charlotte is punished because Tia left.

Yea it's Lua.

Haven't you seen that coming from the very beginning? Author loves him a lot.

Our old demon, father to Ian the demon hunter, and husbando to MC (well not yet, I'm only on ch 80)

...I need to go reread his scenes. He gives me butterflies, I'm glad author gave MC a side to rely on.

Stay with me, it may seem like useless information at first, but you'll understand why.

Basically,

Charlotte was the Duchess's Doll, picked up from an orphanage young and raised as a doll and treated as a doll, not as a person. She grew up warped and lacking as she was solely dependent on the women who treated her like an object. Sometime after the duchess died, Charlotte committed su*cide with her sleeping pills. This was when Charlotte died.

When MC woke in Charlotte's body, it was an unspecified time after the attempt, that time is missing from the story.

MC is a Korean that lives an unloved life where she is alone and a bit poor. She plays a video game to escape her reality for a bit and retains basic information about the world: FL returns in 3 years to kill the villainess.

Now that we have the basics over with.

MC is Charlotte. More specifically, Charlotte's been doing some unsolicited world-hopping.

So you see, this spoiler slightly links with the next spoiler "Truth of the World". There may be some aspects in this spoiler that you don't understand yet because I won't explain it here.

Follow me now.

---- At first, there was Grace. She died.

--------- Grace reincarnated as Charlotte.

---- Then there was Charlotte. She died.

--------- Charlotte reincarnated as Kim Dan

---- Then there was Kim Dan. She was pulled into the game world as Charlotte.

--------- Kim Dan became Charlotte.

So you see, everything loops. Grace is Charlotte is Kim Dan. MC's soul has been on a tour.

Oh, did I mention she's the world's god successor?

And we are here, what we've all been waiting for.

This world is a fun game created by the world's previous god, Grace.

Grace loved humans, and abandoned her staff and duties to live among the humans. She was eventually killed by humans for her godlike abilities, because well, humans be humans. Always afraid of the unknown and uncontrollable.

Grace's staff were the dark sorcerers who helped Grace manage the world's balance of good and evil. Keeping both demons and saints in harmony, proper yin and yang. So when Grace died, the dark sorcerers carried the managing burden and searched for a new successor.

1000 years later, Grace reincarnated in her own game as Charlotte. The dark sorcerers were ecstatic, the boss is back! But then Charlotte killed herself. So shit, things are back in the mud.

The general manager, Lena, one of the dark sorcerers, uses Grace's game to attract souls from a new world to become the world god's successor. One after another, things weren't looking good.

And as Lena was looking for the 100th soul to give "Charlotte" a shot... Bam, found Grace-Charlotte's runaway soul. Perfect 100% match to the body because.. well.. it's her own body.

So Lena stuck it in, and as Charlotte did previously, she quickly hated the world and su*cided again. But she couldn't leave this time because the duchess's will was her tether.

So eventually after becoming more and more warped with anger and depression, MC was thinking "How the hell can I return to reality with this mindset, I won't make it". And well, with that as a good point, she also found out that this was her original world. And that she's a god successor, and the reincarnation of the previous world god....

So, MC is just gonna stay and live freely here. Just getting through the game contents and taking a nice long break with Lena and Lua. Ah. I forgot to write a spoiler for him.

basically cannot die

she makes a contract with the Great Devil

she was in love with her adopted sister/OGVillainess

MC finds out early on that she goes back to her original world once she dies, and that she returns back to the other world when her body is revived there - which is exactly what happens after her first death show in front of all of the OG FL's suitors. This, I can respect as a sort of screw you to the people who'd end up killing her in the original work.

However, she continues gathering all these people at her every death attempt despite their established ability to bring her back forcefully. It gets to a point where it feels like MC's aim is more to spite this group of strangers who haven't done anything more than a mean girls routine at her than to get back to her life - especially when 70% of MC's dialogue is about how everybody loves her sister and no one loves her *sob*, despite her not being a reincarnator/bound to a system/invested in that world at all.

It also bothers me that the MC has enough 'evil energy' to undo an ancient demon's seal despite the villainess being a mean girl who occasionally slaps people and the MC herself having very little established about her. Speaking of which...

For the most powerful evil demon to ever demon, he hasn't really done anything demonic besides brood in a corner. Despite having no love for the other world or its inhabitants, MC uses his demonic powers exclusively as a taxi / consequences deterrent from the OG FL's suitors.

which is possibly why OG FL is probably the most interesting one in the whole story.
