Wen Zhi runs the Wen Group until her sister and her fiancé stage a car crash meant to kill her. She survives, but the accident leaves her with the mind of a small child and no memory of who she was. Wandering the streets alone, she is taken in by Feng Yan, a man feigning frailty to dodge the marriage his stepmother Xu Fangli keeps forcing on him. He marries her on the spot to end the pressure, then finds himself thoroughly undone by her. The people who put Wen Zhi in that car have no idea she is still breathing.
