I Dressed up as the Vicious Female Counterpart in the Ancient Ba Zong's Novel

I dressed up as the vicious female counterpart in the ancient Ba Zong's novel I wanted to lie down, but the system forced me to follow the plot I was not happy at first, but I didn't expect that the heroine seduced my boyfriend's best friend and wore it. Very good, viciousness is inevitable, but who stipulates that I must be the female supporting character who dies tragically in the end!
