Ten years ago, Desy Gusto and her mother were ruthlessly cast out by her father and greedy stepmother. Driven by revenge, Desy returns—only to be framed by her half-sister, Chloe, who forces her to marry Sam Wesley, the paralyzed eldest son stripped of his heir status. Meanwhile, Chloe schemes to marry the newly appointed heir to claim wealth and power for herself.
Unbeknownst to anyone, Desy is secretly a divine physician. She strikes a deal with Sam: she will heal his legs, and in return, he will help her exact her revenge. At the same time, Sam realizes that Desy is the very girl who saved his life years ago.
Guided by Desy's brilliant medical skills and cunning, Sam walks again and reclaims his rightful place as head of the Wesley family. Meanwhile, Chloe and the Gusto family collapse under the weight of their own greed and villainy. With their vengeance fulfilled, their contract marriage blossoms into true and lasting love.
