A former substitute sprinter for the national track and field team, he was marginalized because of his introverted personality. He is good at analyzing game data and loopholes in the rules. After a teammate's drug test scandal broke out, he was pushed to the final stage and was stigmatized by the entire team. He hid a paper appeal voucher left by his father ten years ago, which recorded the shady events of that year and had never been used. At this point, he has to put his career on the line.
