“You said you wanted me to become the Duke’s bride at the age of five?”

Nassia, who used to be an archmage, was reincarnated with an incurable disease.

I thought that I’d be abused after getting sold off in marriage to a Duke who was said to be cold blooded, but he suddenly suggested for me to become his adopted daughter!

I accepted it rashly in order to gain strength and escape, but it turns out that all mages in this world are given the death penalty?!

What if I get caught?

All of a sudden, I was left to conceal and suffer with a big secret.

“You can trust me, Nassia. Most of the things you fear won’t happen.”

They all said that he was a terrifyingly cold-blooded man, so why are you being so nice to me?

The healing romance fantasy of Ain, a reliable but clumsy father, and Nassia, who finds it awkward to trust people!

[28/09/21] hey, it's the translator, mio here!

might be a bit biased here but this story is probably ranked 1st or 2nd in the stories I translate even though I only translate four hALSKDFJDFS it's competing for 1st with selling the main character's shares hAHAHA

it's a really, and I quote from the synopsis, healing and wholesome novel that focuses on breaking down barriers, exposing vulnerabilities and family relationships. Ain and nassia's relationship makes me melt, and so far (i don't read ahead), our MC, nassia, who was betrayed as an archmage... more>> in her previous life, is super realistic in terms of finding it hard to trust people due to past betrayals and trauma. I really like how we can see her thoughts (which we see are more mature due to her memories of her past life), and also how, although she does try to act appropriately to her age as to not seem strange to others, the people within the ether duchy's estate can immediately tell that she's more mature and hilariously misunderstand it as a response to her abuse in her maternal home (which would also be a very realistic and valid reaction had our MC not remembered her previous life either).

so far, it is a very slice of life novel, there isn't any plot yet (though I do think there will be some action later on as mc's adoptive father, ain, is a guardian of the sea of fog, which is basically a cesspool of monsters, and nassia was reborn with her powers as an arch mage. There will probably be a slowburn romance as well in the upcoming chapters too (judging by the way the story is progressing). I'm guessing romance won't be a big part of the series in the first few chapters (at least I hope it won't), since I really want them to flesh out nassia's father daughter relationship with ain first.

this is getting quite long but I do hope you give this novel a chance! Nassia and ain just completely melt my heart.




author would be slapping themselves in the face if it was since its whole premise was that the lebouire barony is so f*cking disgusting for sending a five year old child to take the eldest daughter's place as ain's bride.

to the best of my knowledge, so far, I think they're setting up sir rottier's younger brother, frey, to be the ml. He's also sick and seems to have mana surrounding his heart as well, so I'm guessing that's how they subsequently get closer.

Pretty good so far. Everyone wants to dote on her but she doesn't fully trust them yet. She's sneaking around trying to find ways out just in case. But everyone knows and pretends not to so she can be at ease lol.
