Because technology in the underworld is so backward, Yan Xi asks to enter the mortal world to help her father.
Yan Xi: "Ooh, this is fun! Ooh, this is fun too! Wait, I've got a bold idea!"
Romance blurb:
Yan Xi: "I heard you don't have long to live. I think we should date."
Someone: "Where did that logic come from?"
Yan Xi: "We can have a ghost wedding on the day you die. Isn't that wonderful?"
Someone doesn't think it's wonderful at all, and wants to go meet the King of Hell ahead of schedule.
The King of Hell refuses to acknowledge you as his son-in-law and carries off his precious little girl.
The female lead is the King of Hell's daughter, super cute. The male lead is a sickly genius celestial master.
This is a terrifying (not really) story about what happens when you don't date me properly: I'll call my dad to take you away.
