This story kind of reminds me of the novel 'A Straight Guy's Nightmare' except the MC is an intersex instead of an omega and it's pretty fucking steamy too :p

Here you go
Just a warning though, the story is not very good imo and has rape in it, I suggest to read it only for the smut haha

This story is really sad, but I just can't help but think that she should've resent Kaid more. Even though logically she knows that what he did was right, it's only realistic that she also hate the person that betrays her feelings, killing her parents and burn them in front of her even if the hatred is also mixed with love. It just kind of annoys me that all she felt is self-blame when she has every right to be angry or even hate him.
Not only that, it's pretty scummy of Kaid to not only get close to her, but even date and kiss her even though he knew that in the end he has to kill her family and there's a large possibility that he has to execute her too. Even though he supposedly loves her, he doesn't trust her at all, proven by he never gives her hint on the bad things her parents has done and he never warns her the day before he was going to take action on her family. His past actions are so heartless and ruthless that no matter how well he treated her it just comes off as hypocritical to me :(
Aww I kinda missed Ueda and Aki's main story :q
