"How about giving 200 days of your life in exchange for your mother's recovery?"
Zhou Qi, a patient with depression, stood on the rooftop, with his alcoholic and violent father behind him, and his mother with terminal cancer lying in the hospital. The contract of the mysterious male protagonist Ye Hanchuan is like a life-saving straw - his father will disappear and his mother will recover, at the cost of her remaining 200 days of life.
After signing the contract, Zhou Qi discovered that something was wrong with this demon. He would hand her hot milk when she stayed up late, tie her loose shoelaces, and even protect her from fatal attacks. What's even weirder is that the contract with the iris ring on her hand will make her condition improve and disappear when he touches it, which seems to remind her of the forgotten past.
When lawyer Cheng Yuan found out that all the evidence pointed to "supernatural forces", and when the calendar in front of his mother's hospital bed was torn up to the 199th day, Ye Hanchuan suddenly pressed Zhou Qi on the contract: "Who are you? Why are you... So familiar?"
The bloody memory of the past life breaks through the seal - it turns out that they once loved each other and were separated by life and death, and this contract is a reunion carefully designed by the devil across a hundred years.
"This time, it's me who will die."
Concept: Love is an instinct that transcends time and death. Even if memories are erased thousands of times, souls will still find each other along the scars.
