In my previous life, I was so humble and so timid that I could only cling to life because my wife traded her life for mine. In this life, I have returned as a king. I will give you a lifetime of splendor and a bright future. Those who humiliated, bullied, and persecuted us as husband and wife, listen up: I will make you regret ever coming into this world. I will become your nightmare.
