Lin Xiaomei, a 40-year-old housewife who wasted her youth on family, faces her husband's infidelity and her senior high daughter Tangtang's hurtful words: "You're just a failure who can only cook noodles!" On a rainy night of breakdown, she travels back to 17—becoming Tangtang's high school deskmate! Hiding her "mom" identity, she helps Tangtang fight off bullies and improve math, while secretly preparing for the college exam she once gave up. But when she catches her husband with Tangtang's head teacher, and when Tangtang hugs her sobbing, "You understand me more than my mom," she panics—will Tangtang accept her if she learns the "cool deskmate" is the "failure mom" from before? Is this time travel about reclaiming youth, or learning how to "love truly"?
