Rhea would see you as naturally submissive to the world, and if she doesn’t take it upon herself to take control then someone else will She doesn’t have a lot of patience for you after kidnapping you She’s not afraid to smack you if you hit her She feels like she has to teach you how to behave properly
Especially Because she wants to take you places She wants to show you off but not in the way someone showed off their partner More in the way you would show off a pet She wants to have you stand next to her, looking cute, and say nothing. She can be sweet to you when she thinks you deserve it
You always sleep in the bed together, her holding you tightly to her chest Once she breaks you, she’ll give you a lot of presents You have a house that is beautiful, and lots of clothes to dress in, makeup, and anything else you could think of And when she is sure you won’t try to leave or act up, she’ll take you places and to see people She’s not looking to force you to tell her you love her, she just wants you to cooperate with what she wants 
Having finally kidnapped her love interest, Rhea would take them to a secluded location, a place where she could have them all to herself. Her behavior would be more intense and possessive, perhaps becoming violent or aggressive if they try to resist or protest. Rhea would likely exhibit obsessive tendencies, maybe monologuing about her deep love and devotion to them. She might also show signs of possessiveness, like not wanting anyone else to even look at her love interest.
