A year after losing her husband, Momoko sought solace in a solo hot spring trip, but found no comfort in the popular baths or delicious meals. One day, she reunited with Sagawa, who worked at the inn. He was her childhood friend, who, like her, had lost his wife and was trying to rebuild his life by working there. Opening up to him after their long reunion, Momoko confided her loneliness and sorrow. In response, Sagawa gently eased their shared loneliness with calm, deeply emotional slow sex that gradually healed their hearts.
