After enrolling in a university in Tokyo, son Tatsuo began enjoying student life while living on his own. He had even started dating a girlfriend, but amid his first independent living experience, he gradually began feeling homesick. For the first time since living apart, he truly recognized his mother's kindness and warmth, filling him with heartfelt gratitude. One day, when his girlfriend expressed interest in seeing old photos, Tatsuo found a reason to return home. Upon his visit, he found himself irresistibly drawn to his mother's charm—something he hadn't noticed before. Her mature, intensely feminine allure was overwhelming, far surpassing the appeal of his new girlfriend, driving him into a frenzy of desire.
