I Avenge My Love-Minded Sister Who Died Tragically

Looking for Time Travel, Sweet Pets, Sadistic Stories, Pure Love, Short Stories of Revenge,

I would like to read a book similar to "After passing through the book, I became the boss's favorite". 1. It's over. I actually traveled back in time to the vicious female partner who drugged the boss in the book! The beginning is hell difficulty. Rating 9.8 2. The patient I met ten years later turned out to be me.
