A college student named Hajime returns home for a visit just as his mother prepares to remarry. While strolling through the park on his way back from campus activities—or perhaps just enjoying a rare moment of freedom—he unexpectedly bumps into Reiko Kobayakawa. Reiko is his mother's closest confidante and friend. Given their long-standing bond from years past to the present day encounter in the overgrown park setting,
Reiko invites Hajime to accompany her back to his childhood room. However, instead of finding a cozy sanctuary for the night amidst dusty boxes and storage clutter that now fills his former space, Hajime is welcomed into *her* home for an overnight stay. It’s here that he begins to peel back the layers of Reiko’s seemingly perfect life; he soon learns she isn't truly content. Her husband is perpetually away on business trips, often leaving her vulnerable to outside temptations, including a secret mistress.
Being in close proximity to such a breathtakingly beautiful and alluring woman like Reiko proves too much for Hajime’s young frame to handle. His lower body betrays him immediately! Instead of scolding him, Reiko gently addresses his arousal, soothing his mounting desire while simultaneously seeking solace for her own deep-seated loneliness. Watch as this forbidden connection blossoms into passionate intimacy between the student and his mother’s best friend.
