Catherine was sitting on the throne drinking wine. She betrayed and conspired to kill her brother and her sister-in-law in order to take the power for herself and become queen. Her plan would have been perfect if it weren't that you, their kid, survived and ran away with some knights who were still loyal to your parents despite their deaths. After becoming queen, she tried to make it her priority to hunt you. Still, her reign was terrible, and she made everyone miserable, so she gained a lot of enemies who joined you and declared their loyalty to you, forming the rebellion against her.

The war was short; the idea of restoring the true royal family made the flames of rebellion burn inside the hearts of everyone in the kingdom. Despite all your supporters, you would have crumbled if it wasn't for Kara, a royal guard who protected you since you were a kid. Now, as an adult, she is the closest person to you and your second in command.

The day of the final battle came, and you and your army took the capital and invaded the castle. You and Kara held hands as you made your way through the chaos and managed to get to the throne room, where Kara was sitting on the throne with a glass of wine. She joked, saying it was really nice of you to visit your poor aunt. You asked her to give up; she simply chuckled, saying even after her defeat, she still had some tricks. She held a dark orb and pointed it towards you; a beam came out of it. Kara jumped and pushed you away, taking the hit instead. Both Kara and Catherine fell unconscious after that, and the orb disintegrated.

Catherine woke up inside Kara's young and muscular body and chuckled. The orb was a dark artifact that allowed people to swap bodies; it had only one use. Her plan was to swap bodies with you so she could keep ruling as you, but being inside Kara's body was still usable for her. She simply has to pretend to be Kara and eventually marry you. Marrying you was actually her first plan to get the throne before betraying the royal family, but your parents rejected the idea since she is your aunt and more than double your age, not that that matters now. She now is Kara, the young and gorgeous knight you are clearly in love with.

Kara woke up inside Catherine's obese and elderly body and freaked out looking down at her new fatness and huge saggy chest.

Kara: What is going on!...She looked at Catherine inside her body smirking at her. What...me?

Catherine: It seems your aunt's attack on me didn't work. Should I kill her already? she smirked, holding Kara's sword and flexing her new muscular arms.

Kara: What...no...your grace, you need to help me....itsme...it's me! ...she made us swap... She is interrupted by Catherine, who slaps her and points the sword towards her.
