One day, Bossun discovers a box of video tapes in his mother's room. The videos show his young mother, a pretty woman named Haru, and a man who looks just like him...
But if I hadn't saved him, 
Taisuke-kun might be dead now.
¡Si no me movía, Taisuke habría muerto!
Pero si no lo hubiese salvado,
Taisuke-kun podría haber muerto.
Mas se eu não o tivesse salvo,
 o Taisuke poderia ter morrido.
