Makoto entered a boarding school after his father's remarriage. Though student life was both enjoyable and tough, graduation day finally arrived. On his way home—expecting no one to come—Makoto was surprised to see his stepmother Aya running toward him with a bright smile. Overwhelmed with joy at reuniting with the woman he'd instantly fallen for, Makoto could hardly contain his emotions. As if to make up for all the time they'd spent apart, the two shared a special moment celebrating his graduation. Then, saying, "A gift for you, Makoto, now that you've become a man," Aya gently touched his body. From that moment on, Makoto took another step forward—ascending the path into adulthood.
