So the bloodline is actually Incest. Yayyy! ain't that fun. and the doctor wants the duke to have another child (probs girl) to have incest with his son? something like that
Since he can't get the duke to do he tries to get close to Vivian/Lucia. He tries to sneak.
There’s a translated Webnovel you can check out if U want? Spoilers
He also tries to take Lucias child away. Since he told the duke the only way to have kids was this other method he had hoped that once it was discovered she was pregnant the duke would think she had an affair. Then once the duke kills her he would take the child and raise it until Damian (son/ nephew) was of age and then bring her to him. Of course his plan was foiled but still. He’s obsessed with the duke bloodline
......so "genitals" is the most vulgar word in her vocabulary? Seriously?
