Three years after breaking up at university, Lin Xiaoyu, a 22-year-old corporate drone, accidentally transmigrates back to the first day of high school at age 16 after getting drunk. Faced with Lu Chen, the aloof upperclassman she remembers as “the guy who'll cheat on me with the belle of the math department in the future,” she makes a vow: “This time, I'm taking charge of my love life!” But the harder she tries to avoid a bad ending, the more she finds herself in face-slapping “chasing my wife (strike that), chasing my husband” situations: like stepping right on her senior's dietary taboos in the cafeteria, ruining a relay race with her “foreknowledge of the future” at sports day, and even putting on a spectacular “I'm not interested in men” act in front of him, only to fall for him anyway... And so begins a campus comeback battle with an “inside view of the future” that's full of holes!
