Reborn in the Beast World, My Best Friend Traded Her Health for My Beauty

My best friend and I were both born into the Beast World. By a stroke of luck, she obtained an exchange System. She said she envied my beauty. In the tribe, I was adored by everyone and always the center of attention. Once I came of age, I married the leader of the wolf tribe and had nothing to worry about for the rest of my life. She, meanwhile, could only hide in the shadow of my radiance and envy me in silence. So she traded her health for my beauty. But she didn't know this was the Beast World, where beauty was practically an invitation to be violated! Unless she was ready to endure the torment of people possibly forcing themselves on her at any moment, despite her poor health! Thanks to her, I got a second chance at life and became the High Priestess who united the entire Beast World!
