Go Back to Before Being Killed by Your Sister and Pamper Her Wildly

After not seeing each other for many years, my sister was forced to become the boss's canary. After she came back, the first thing she did was to take revenge on the whole family. She was so angry with my grandma that she reported it to my parents. She even broke my hands and feet and threw me into a dark basement where I was tortured every day. When I was dying, I reluctantly asked her why. Why did she torture me like this when I obviously didn't do anything? "Why?" She just looked at me coldly, "Of course you didn't do anything." "You just watched with cold eyes, and used the money from me to study and marry with peace of mind, and sucked my blood to survive until today, but you can obviously do something..." When I opened my eyes again, I went back to the day my sister was sold. This time I no longer pretend to be stupid and knock out the bastard who wants to occupy her with a sap. "Sister! Don't be afraid! My brother is here to save you!"
