As graduation looms closer, two friends spend time with each other to forget the ache of what might happen after.

Li Beibei, a "humanoid power bank" whose heart rate exceeds 120 and generates a strong current, unexpectedly met Zhang Wei after picking up a comic drawn by Zhang Wei, who had a crush on the school flower. The two of them helped each other pursue the "male and female gods" in each other's hearts as "tool people", gradually approaching each other without interruption. Finally, at the final of the campus relay race, Zhang Wei faced his inner voice and said the long hidden words to Beibei.
