The viscount's son, with whom she already has a son, is her daughter's father. She was already pregnant with a her daughter when she escaped her slave life in the viscount's house.
And to make it CLEAR, author will NEVER tell us who REALLY is the daughter's father between Alan and Sovieshit, because Ergy will fake the blood tests but even that isn’t sure.
Sovieshit ate the cookies, so he should be barren. The daughter was born at 7 months but was perfectly healthy and not premature at all. The daughter looks EXACTLY like Rashta so her looks doesn't tell us who is the father.
Until the end who the father really is wont be known, but there's like 70% chance it's Alan's and 30% chance Sovieshit's
Yh I remember Heinry saying he knows he’s loyal but he always goes off on his own plan, and he told Navier not to worry about him cause he’s on her side but she’s not allowed to fall for him lool
I’ve been waiting patiently for him to reveal his hand, all these little things make them or in a way the empire look bad but why. This chapter gave us a big clue tho, the beachside property!? At first when he said he’s not of nobility son he’d have trouble and no support as her Lover, I was like huh, does he want to take the throne for himself?
But I think he wanted the beachside land the whole time and it’s a part of his plan.
I’m so excited for his plans to go through cause I feel like he’s the only real reason we’re getting revenge. I think trashes would’ve continued playing innocent and the sovshitzu would’ve been the only one manipulating her, as he said, and they probably would’ve carried on in their delusional love bubble until him being infertile came to light and navier having kids the envy he would have would’ve been our only joy.
Now with Ergys help… everything burns
HAHAHAH YES I AM LETS GO.
SPOILER****
When.sovieshit was a kid, his father brought in a mistress, and that made Sov's mom depressed. Sovieshit, thus, hated his father for cheating on his mother and bringing in a mistress (the audacity).
Sov's mom, the empress, was going to give the mistress infertility cookies so that she would never have babies, but Sovieshit that dumbass took the cookies and ate them with Navier. Thats why they couldn't have kids. Sovieshit made Navier barren.
Now, now. Sovieshit, after learning what the cookies are for, told his father THE MISTRESS TRIED TO MAKE HIM BARREN (she didn't obv). Sovieshit's father, by Sov's lie, banned the mistress from the empire, and she had to run away to a foreign country.
After travelling by boat, the mistress met the grandduke of another country. The mistress looks EXACTLY like the duke's sick wife with poor health. The grandduke asked the mistress to act as his wife in front of the nobilty and to live in his home to pass for his sick wife.
The duke's real wife is a very sick woman who could never attend any social places due to her health, and the duke wants to use the mistress (litterally vopy carbon of his wife) and make ppl think his wife is healthy and fine.
She accepts, and goes to his house. And in this house, there's a little boy, Ergi. Ergi, who loves and worries for his mom, hated his father from the moment he brought the mistress home, and even if he didn’t have anything against her at first (i believe), when he realised she was here to TAKE his mom's place, who is almost dying in his room, starts to loathe her.
The mistress will fool everyone and all will believe her to be Ergi's mom, and his biological mom will be more and more exluded from her own place and title. She will be sent in that cottage not far from the duchy 'for her health' and will be forced to leave the duchy. After that Ergi will hate his father and his mistress forever.
At some point, either before or after Ergi's mom leaves for the cottage, a fire will happen in the duchy, and the mistress will get a scar on her face (again, i believe) through saving ergi's life who was still in the mansion. Even if she saved his life at some point, Ergi will grow to hate them for what they did to his real mom.
The mistress, to this day, even when Ergi is a grownup, is the 'duchess'. For everyone, SHE is the duchess. His real mom is still in that small house, very sick and suffering due to her health.
Ergi KNOWS the mistress came to his house and stole his mother's place because Sovieshit LIED to his father and made his father exile the mistress. Ergi's DEEP HATRED towards his own father, his mom being excluded and alone almost all the time, the mistress stealing her place, is all Sovieshit's fault.
That's why he came to the empire and uses Rashta. He will destroy Sovieshit. He will weaken the power of the eastern empire, steal the imperial port through rashta, and make Sovieshit miserable like his mom is. He will also be the one who will make sure no matter what the resaults are, it will be announced Rashta's baby isn't Sovieshit's. (That's why we will never REALLY know who Rashta's 2nd baby daddy is. Sovieshit or Allen.)

They are BOTH infertile (BC OF SOVIESHIT) but Heinry's bed contains magic and Navier becomes fertile again thanks to it.
