Once she was reborn, Su Mian realized that the one she had ravaged in her previous life was actually the son of Lingji, the King of Demons. In his previous life, he became a cruel and psychopathic demon king who killed all the "evildoers" in Lingcheng. She also became a thorn in his side and a thorn in his flesh. She was tortured and died miserably.
After reviving her life, she decided to change her ways and be a good person...
"In the next life, you should be a good person."
Intention: A broad agreement between life and death, discussed with Zicheng
