On his way home, when no one was supposed to be there, a woman comes running towards him with a smile. It's none other than his stepmother, Shoko. Atsushi is happy to be reunited with the woman he admires. Just the two of them are celebrating the graduation, and Shoko, tipsy, gently holds his cheek and says, "I'll give you a graduation gift..." and softly kisses him... And he takes another step towards adulthood.
