As a young man who had always been fast on his feet, even during childhood, and was highly recommended for track and field due to his speed, I found myself well-regarded within my team. Recently, I started dating another girl from the same track and field club, Suzu-chan, and things were going great... until one day, when a senior member of our team began harassing me for some unknown reason. Feeling cornered by the relentless bullying, I eventually agreed to a devilish deal proposed by the senior, which resulted in losing the most precious thing to me - beautiful Suzu-chan.
