I was the ace of the baseball team until a severe injury left doctors telling me, "You'll never play baseball again." Plunged into despair, my father crushed by guilt. The only one who stood by us was my girlfriend, Mizuki. She encouraged me, gave me strength to keep moving forward. I swore I'd never give up, making a promise straight out of a shonen manga—to take Mizuki to Koshien. But behind that promise, Mizuki was secretly meeting my father in my hospital room while I was away. Worse, she was repeatedly having threesomes with unknown male patients.
