Designer Xu Yan suddenly faints while preparing dinner for her husband, Chu Yan. When she opens her eyes again, she finds herself in the office of an unfamiliar branch company. Her soul has transmigrated into the body of a colleague who died suddenly. Good grief, is she dead or not? To uncover the truth and return to her family, Xu Yan uses her abilities to secure a transfer to headquarters, where she finds a chance to reunite with her husband. But whenever she tries to tell him who she really is, she faints and wakes up on the high-speed train bound for headquarters, trapped in an endless loop...
As Xu Yan and Chu Yan work closely together on a joint project, her unconscious design habits and little details of her daily life make him suspicious of her behavior. During a casual chat with a colleague, Xu Yan is shocked to learn that her original body is still unconscious in the hospital! Even more devastatingly, when her original body regains consciousness, Xu Yan discovers that she has not returned to it!
After waking up and leaving the hospital as “Xu Yan,” the other woman gradually grows attached to a life surrounded by love: a considerate husband, doting parents, a well-behaved son, and even better career prospects. Xu Yan is eventually forced to move in with the Chu family as a “best friend,” watching helplessly as this outsider enjoys the life that should have been hers.
As two women struggle against each other and one man awakens to the truth, who will truly take hold of time's reins? Will they find the light of reunion, or face another cruel loop?
“Fate made me trade lives, not to steal, but to teach us how to see our own souls through someone else's eyes.”
