Disfigured Daughter Returns Home: Poisonous Doctor Takes over Kyoto

My stepmother disfigured me and abandoned me in the mountains. I don't want to die, and I have developed the skills of poison and medicine. On the day I returned, I raised my eyes and smiled - those who abused me back then will pay them back a hundredfold. The cold-faced prince follows me every step of the way. Everyone is afraid of him, but he only protects me.
