Looked up the novel for spoilers...
Wahhhhhhhhh it's sad... The story is sad and the ending is also sad... They don't get a happy ending and Dietrich doesn't remember her. On top of that the Dietrich she meets outside is different.
On top of that. Noah is her child, but she doesn't remember him. He ends up disappearing to save his mom... I might drop this it's very depressing

Yes .. but Dietrich loses his memories after he escapes. So Charlotte is the only one who remembers. Noah also ends up disappearing because the curse on the mansion was broken.
The story still continues for like 100 chapters after though, and a lot of people say the story deteriorated after that point.

SPOILER
so I looked into the spoilers after seeing your comment. And you were kinda right but a bunch of other stuff also happened. The ending is technically not a sad ending, as Charlotte and Dietrich do end up together, it's just an open ending since you don't know wether or not he still has his memories. And yes Noah does end up disappearing, but after he disappears and charlotte leaves the mansion she becomes pregnant with another child, and while this could very much not be noah, because of other circumstances she would like to imagine it's him.

Tl;DR: SHE DOES NOT RAISE HIM. SHE MEES HIM WHEN HES 8, HELPS HIM OUT, GETS TRAPPED IN A DIFFERENT DIMENSION AND WHEN SHE COMES BACK HE HAS GONE CUCKOO BANANAS.
Is it a kind of weird premise? Yeah. But worse marriages have happened in history and worse FL/ML pairings have been done, where the FL LITERALLY RAISES the ML. (Looking at you, I raised the tyrant and ran away, looking at you, I became the dukes maid, looking at you that hansel and Gretel witch one, and also literally every go back in time/reincarnation story where the FL becomes a child again)
But she rejects the marriage because he's a child and only ends up going through with it because surprise, he's an 8 year old duke who can be easily manipulated through marriage, so she decided to stay by his side to protect him. There isn't any romance during this time.
Her original plan was: after he didn't need her protection anymore she wanted to find him a nice wife his own age and then go off on her own to grow flowers.
Honestly, if the whole trapped by dark magic things didn't happen that's probably how things would've gone, but unfortunately her disappearance was the last straw in his sanity and he got really obsessed and when she comes back he is certifirtifiably insane.
People overusing words like gr**ming takes the meaning out of the word and muddles the very awful details it actually entails. She knows him for like a month and then basically is in a time comas for ten years. That's not grooming. It's just kind of weird. But every time travel reincarnation romance is kind of weird, but suddenly when the FL looks her age it's not ok anymore?
Anyways. My point is, this one actually isn't that bad. If has interesting lore and the FL is a great character. I rate it 5 stars to offset the review bombing from people who didn't bother to read it.

They’re all so dumb but I love it *coughs blood*
I’ll just read it like it’s a comedy ╮( ̄▽ ̄)╭

Me too. I cried so much after she offed herself (I think I was having pms too, lol). But now it's so much better! I bet even then the prince was sent by her father and was only faking it so they'd let him in and he could help her escape or ask her important stuff to find the real culprit so they could prove her innocence... :-C

Ml is a manipulative liar but to be fair there’s probably a lotta stigma surrounding demons and he probably feels like he can’t tell her or she’ll hate him. Doesnt justify what he’s doin but I’m looking forward to see how he’s gonna (or if he’s gonna) redeem himself from this. Let’s just hope his bad actions will actually be acknowledged and addressed ╮( ̄▽ ̄)╭
I don’t think Aqua and Goro are different people. Aqua was Goro, Goro became Aqua. Aqua just happened to be born with memories of his past life, but I don’t think this made him any more Goro. Just like the crow girl said: he was just a kid who was born knowing too much.
It’s a good take on reincarnation imo, and it would be crappy to see goro “die” and aqua live. We’ve spent so many chapters exploring Aquas struggle with his identity and finally come to the conclusion that he is just himself.
I think the only reason aqua ever became so obsessed with his memories is because seeing Ai die in front of him was obviously very traumatizing, so he convinced himself he was really a grown up and put all this responsibility on his shoulders when he was really just a kid. And the tragedy of it all is that some horrible persons actions ended his life before it could begin, first when Ai died, and again when Aqua dies.
Kinda like pokemon evolving, no? Sure they're one thing now, but that's doesn't mean they don't have the experiences they had in their original form
