>Six months ago, I had finally confessed my feelings to my childhood friend Suzumori Mizuki, who was a tomboy and had been messing around with me since we were little, and we had been in a pure relationship ever since. >Then, in the summer of the year I was about to graduate from school, I kissed her and made a promise. "I... will continue... after I graduate!!" >Mizuki, who is the ace of the track and field team and has a bright future, was busy with training camps and tournaments throughout the summer vacation because of our promise to go to the same university together. >One month later, a DVD with an unknown sender arrived for me. Normally I would have thrown it away, but out of strange curiosity, I decided to play it. >On it was the image of my girlfriend Mizuki, who had been seduced by the track and field team's advisor!
