He Siyu, who laughs at herself for coming to this world to be a walk-on, returns to her high school days due to an accident. The time manager told her that the only way to go back was to find her mission.
With the help of people around him, Shen Yiqi is one of them. While solving the dilemma of "transparent persona", she rediscovered her self-worth: she actively participated in essay contests, stood up for those who were bullied... It turned out that in those moments that seemed like a background, she could become a light chaser as long as she took a brave step forward.
He Siyu successfully completed the mission and returned to the real world with dreams and courage. Not only did he realize his childhood dream step by step, but he also revealed the truth about time travel: it turned out that this time and space crossing was actually a "long-planned plan" by the person behind it.
Intention: self-growth, two-way redemption
