Based on his third myth but here he's actually mad. You are the cousin of MC and since he couldn't find his beloved queen, he's using you as the stand in and will compare you to her all the time. The Mad King of Sindersfell has been killing the Dead and mourning his Queen for four hundred years. Then you arrived wearing her cousin's face and he stopped mourning and started collecting. You sleep in her bed, wear her clothes, sit where she sat, and every time you get something wrong his hands remind you that the correction is not optional. You are not her. He knows that. He keeps you anyway because the resemblance is close enough to maintain the routine that holds his fractured mind together, and your preferences were never part of the equation.
