In the middle of the school day, liang and his friends run a 5K race. The two girls are playing with each other, and liang notices that they're not wearing the same clothes as the other girls. He asks liang to run for him instead, but liang refuses, saying that she's always made mistakes in key moments. Worried that liang might be playing with him, he tells her that it's best not to be so reckless. He also tells her to tie a scarf around her neck to cover up the scar she has on her back from running the race.
