But on their wedding night, Xiao Huaizuo's old illness flares up, and Ye Li nearly gets buried alive at his mother's command. Fortunately, fate doesn't let Ye Li die a second time.

Xiao Huaizuo says, “I was never going to live much longer. Giving you your freedom is the last thing I can do with my life.”
Ye Li says, “You have to believe me. I came here from another world. I may not be able to stay for you, but I can definitely cure you.”
Two hearts pursuing one another, saving each other, and finding their way back together.
