It was eight years ago. Yuki, working as a home helper, was assigned to care for an elderly man named Yamada. He was a lecherous man who often made sexual advances, and his behavior had left Yuki thoroughly annoyed. Yet beneath his crude exterior, there was something oddly endearing about him. Time passed, and Yuki eventually married and became a housewife. One day, by chance, she passed near Yamada's house and felt her heart race. She decided to visit him and found him unconscious inside. Seeing him in that state, her heart ached, and she resolved to do something for him.
