Reborn as the Poisoned Princess

I helped him become emperor, and he ordered me to be torn apart by five horses. I gave him my youth and poured my heart and soul into him, yet he called me a poison concubine, a wicked empress. I don’t blame my best friend for betraying me or that scumbag for being heartless. I only blame myself for being too naive in my previous life. This time, every one of you villains will pay in blood!
