My Brother Saved Him, Then He Killed Me——Reborn to get even

My brother died saving the mafia boss and entrusted me to him. He repaid that trust by torturing me and throwing my half-dead body into a dumpster. Then I woke up on the day he proposed to me. Everyone thought I'd cry tears of joy and say yes. Instead, I smiled. The mafia boss wanted a helpless bride？

Too bad. I came back with Superhuman Strength. Now it's time to make you pay. But wait... why did the crippled fiance I chose suddenly stand up? And why is he looking at me like I’m his?
