I had been aiming for the world championships in swimming when I suddenly received a dismissal notice from my company… The reason for my dismissal must have been that they caught me having sex with my college ex-girlfriend (Otoha) and the swim team coach (Matsumoto) in the locker room… The coach, who has a wife and kids, must have fired me out of fear that his affair with Otoha would be exposed. Having lost my purpose in life and hit rock bottom, I investigated Otoha's daily habits and broke into her company dormitory with some bad friends. To vent all the pent-up grudges and take thorough revenge!
