Shiro Ken (Hidetoshi Nishijima) is an experienced lawyer. In the eyes of his colleagues, he is handsome, professional, over 40 but still single, just like a diamond bachelor. But in fact, Shiro is a homosexual and is living with his lover Kenji (Maiyo Uchino) who has been dating for many years. However, he has never made his identity public. For Shiro, the most important thing every day is cooking. Therefore, he always tries his best to complete his work tasks within working hours and never works overtime, just to be able to purchase the discounted dishes of the day before the supermarket closes, and through careful calculation, the food expenses of the two are controlled within 25,000 yen. Shiro and Kenji have long passed the honeymoon period, and they get along as naturally and tenderly as an old couple. However, even in the calmest life, there will occasionally be some twists and turns. In the hesitation and confusion, the healing power of food is particularly important.
