Song Jinan, who was killed by Lu Yanzhou and his best friend in his previous life, was reborn on the night of the engagement party when he was 22 years old. She decisively broke the engagement, but the next day she learned that Lu Yanzhou had suffered a car accident and lost his memory, and he could only remember her. Lu Yanzhou's family begged her to temporarily take care of him who had "amnesia". Song Jinan agreed with a sneer, wanting to see what kind of show he was going to play. From then on, the two started a daily routine of "I know you are pretending to have amnesia, and you know that I know, but we both pretend not to know."
