Hezi, Forced to Transmigrate

Hezi was the younger sister of a certain villain, and had a fairly happy childhood. Unfortunately, when it was time for her to get married, she secretly ran away and ended up transmigrating to another world. Once she'd gotten used to life there, the god of fate played a cruel joke on her: that's right, she transmigrated back. And she nearly took her own brother's head off.
