Soo.. he somehow made her orgasim using magic. Which in turn confused her thinking its love for him. So its kinda mind games a little. Probably whenever she feels sexual pleasure, she thinks of the MC from now on ?
Other than than, I was actually hoping he'd turn the bitch princess into his loyal servant behind closed doors too (like the maid). Then have his spy in the royal family like that. but I guess it was interesting enough with what he did to Sophia.
Thank you for translating this, its going to be a fun ride. :3
