Song Zhaozhao made up his mind to divorce, but a fierce quarrel broke out with his mother Liu Yan.
Liu Yan took away the car keys and indirectly caused Song Zhaozhao's death in a car accident on the day of the divorce.
God gave Song Zhaozhao a chance to be reborn and let her go back to a month ago to exchange bodies with her mother Liu Yan.
A series of mysterious numbers are engraved on the back of their hands - a countdown to death.
When the number reaches zero, the human soul dies along with the body.
Song Zhaozhao's death countdown is 30 days, and Liu Yan's is 3652 days.
On the last day before his death, Song Zhaozhao could choose whether to change his body or not.
Instead, the soul dies along with the body;
If she doesn't change, Liu Yan will die for her, and she will spend the remaining 10 years in Liu Yan's body.
Purpose: cherish the present moment
