Su He, a modern working woman, comes down with a “mysterious illness” that science can’t explain. It feels as if an iron chain is tightening around her chest, and the pain is unbearable.
All her test results are normal. The trail eventually leads to a haunted house she helped air out, and a clan of “ash spirits” she accidentally saved when she was a child.
To put an end to this life-threatening entanglement, she clings to a descendant of the ash spirits: a handsome, powerful man who hates trouble and just wants to quietly “cultivate immortality.”
“Saving you was a kindness. Not saving you would have been my duty. Got it?”
“But that kindness could be the difference between life and death for me!”
She’s the debt he can’t escape. He’s the only cure she has.
