Tatsuo, the son, began attending university in Tokyo and living alone. While enjoying student life, he felt lonely from his first experience living independently and suffered from homesickness. During this time, he met a girlfriend and started dating, but being apart made him gradually realize how much his mother meant to him. He rediscovered the warmth and kindness of his mother, Yukie Miyamae, and began to feel emotionally fulfilled. When his girlfriend expressed a desire to see old photos, he decided to return home for a visit. A few days later, he came back home with her, and upon their first meeting, he found himself deeply captivated by his mother's charm.
