Kazuyo Tashiro and her husband remarried and have been together for 15 years. Both have extensive experience living abroad, meeting at a bar popular with foreigners. She worked as an interpreter, while he was overseas for studies. Sharing similar values and outlooks on life, they married within half a year. Now, before her husband retires and they move to Malaysia, they embark on a journey to visit hot springs across Japan—a trip that deepens their bond.
