After a car accident, Shi Yu returned to the age of eighteen with memories of her past life. In her previous life, she saved people by mistake, paid her sincerity by mistake, and ended up in tragedy. After her rebirth, she deliberately avoided all the points where she could meet him, devoted herself to protecting her grandma, studying law deeply, and living a stable life. By chance, she met He Yunqian and informed him of the hidden dangers in advance, and the two worked together to avoid many disasters. He Xizhou, who was also reborn, was repeatedly entangled in dreams from his previous life. He suddenly woke up and struggled to recover, but it was too late. After all kinds of entanglements, Shi Yu let go of the past and stayed with the gentle and sincere He Yunqian, each heading for a happy life of their own.
