In reality, Leah has been brainwashed by the Queen who is her stepmother. This woman controls everything about the Princess. From how much she eats to her behaviour. This is done through mild starvation, physical abuse and magic. All of that has resulted in a nearly completely broken woman who believes her only way out is to become a "spoiled product" by having s*x and then fully intends to kill herself.

The ML's intervention is to screw the will to live back into her which surprisingly works.

Ishakan is actually the most extreme version of a Kurkan. To the point that he is immune to magic spells and practically loses his reason when it comes to s*x with the MC. During their wedding ritual, he had to be chained to a pillar because it put him in a rut like a beast. And yes, he does knot her. Apparently, his pen*s swells because it is described as looking like a normal one.

This kind of s*x is also the only way for a Kurkan to reproduce which means they can have s*x as much as they want as long as they don't lose their rationality (or whatever you want to consider the equivalent here).

The ML's body fluids are potent magical ingredients that can be used to reduce other spells. So, his sorcerer suggests that he regularly feeds the MC his s**en. Which is not something I ever thought I would write out.

The author wrote the MC as unconscious for the entire escape from Estia to the Kurkan capital. I do get it, writing a journey with nothing happening is pretty boring but it was just strange. The second time jump was clearly because the author did not want to detail how the MC was now fawning over the Crown Prince (who really only has one thought and is dedicated to possessing the MC).

It just makes the story feel a little disjointed as we are quickly told about how they were acting and how the ML was losing his mind over the MC.

Also, the spell to switch her love from the ML to the Crown Prince was interesting but at the same time, really weird. It completely erased the traces of the ML from her mind even though he's a diplomatic figure that she would have known about since he was the King of another nation.

The Queen also brainwashed all the nobles but like everyone seemed to forget that the MC had become the Queen of the Kurkans (or that she had been kidnapped by the ML). Even the poor people forgot it.

All of the front line guys who were sent to kill or capture the MC end up getting killed by the ML or the other Kurkans. The ML is very fond of ripping people apart with his bare hands.

One of the Crown Prince's concubines tries to have the MC violated to "put her in her place". This results in the ML ripping her head from her body off-screen and giving it to the Crown Prince.

The Crown Prince gets stabbed in the heart by the MC.

The Queen loses control of her power after her son's death and ends up stabbed by the ML with a special sword which prevents her from using her magic. He then rips off her arms. She then gets to spend the next however long (it's not specified) as an armless beggar in the streets of Estia's capital. Eventually, she is brought before the MC who then gives the order for her to be killed but leaves it up to her Kurkan followers to decide. It's implied that the Queen is brutally torn apart slowly.

We now know that all this time she (and seemingly the entirety of the kingdom) are under Cerdina's influence.... but still, if the power meant she had no will of her own and so could not kill herself, WHY go to brothel (and increase the possibility of contracting STD, I mean I guess they don't have venereal diseases in fantasy land) of all places? Certainly with her dainty yet icy looks there would be no shortage of potential lovers?!?!?!?!
