A car accident causes Jiang Ning to suffer from dissociative amnesia, with her memory constantly resetting. Mistakenly believing that her marriage with CEO Zheng Heng is merely a loveless business alliance, and even misidentifying her treating doctor Cheng Man as Zheng Heng's "white moonlight," she opposes him at every turn, creates a scene at a night club, and even insists on a divorce. Facing his wife's resistance, Zheng Heng endures heartbreaking pain, and every time his wife forgets him, he plans meticulously to win her back again. When the medical record reveals the truth, Jiang Ning realizes she has long been enveloped by his deep love. Memories may vanish, but the instinct to love you will not; this time, it is her turn to love him.
