I moved to Tokyo to start a business, but it failed miserably, and all I was left with was debt. At a loss, I practically ran away from home and returned to my parents' house, where my childhood friend and step-sister, Akari, welcomed me. "You've become more mature," she said to me, feeling pathetic, but she was just as kind as ever. "Get out of here!" My brother went on a business trip, furious as a raging fire. Unable to suppress my hidden feelings, I pushed Akari down.
