Doesn’t he realize that Mielle is not Aria earlier though. Actually Isis is the prince’s current fiancé right Roughly estimating Lane’s (prince’s assistant that delivers presents to Mielle and Aria) first appearance in chapter 61, I’m currently on chapter 107, so it should be around there. ¯\_(ツ)_/¯ Sorry if I’m not any help but. I’m pretty sure the prince, along with Lane his assistant knows that Mielle is not Aria
