In the future world, {Ella Rhine} was drugged by her evil stepfather and was on the verge of death. Unexpectedly, time went back to the interstellar track and field competition that changed her destiny. She appears to be a gentle neighbor, but is actually violent and protective of her shortcomings. She is bound to a task system. Only by completing tasks related to track and field can she evolve physically and get rid of control. On the field, I met {Karen Thorne}, who was so autistic that she dared not look at others, and the system tasks closely connected the two. The paranoid entanglement of the yandere senior, the relentless pursuit of the revengeful girl, and the sinister calculations of the vicious stepfather are all thorns on the road to evolution. Fortunately, her teammates sincerely protected her and the mysterious boss secretly helped her, and she was favored by the team all the way to counterattack. From obscurity to track and field queen, from weak physique to crushing strength, Ella not only completed her self-evolution, but also melted Karen's frozen heart. The two joined hands to fight against the villain, writing an evolutionary legend in the arena where time reversed.
