How is he using her? Well, the emperor poisoned the Dukes wife, Juvels mom, and made it look like the duke killed her in front of Juvel, she passed out and got seizures, so Duke asked for medicine to remove her memories, but the issue is that she often faints, cue ch4... The Duke has to force himself to stay cold to his daughter so the emperor wouldn't play with her too much, however, Mikhail is the emperors accomplice, and they used that bastard to make Juvel obsessive over him, then he seduced the princess, and well, you know the rest....
