Taisuke Aono lives in Niihama, Ehime Prefecture. All he knew how to cook was burnt chicken and yakisoba filled with vegetables. But when his daughter Nat-chan started high school, he decided to start making bento boxes for her. Nat-chan didn't think he could keep this up for long, since he couldn't stick to a diet, or quit drinking and smoking. And the first bento box he made was a mess... But her dad kept cooking in the kitchen morning after morning. All of his bento boxes came with a handwritten menu. He would give each bento box a title, like "Wimbledon" or "Motivational Katsudon Bento," and would write about Nat-chan's club activities, her tests, events happening in Japan, and updates about his diets. For three years, he kept making bento boxes and writing menus. These menus soon became letters from father to daughter. It wasn't long before he'd made 100, then 500, then nearly 700 lunch boxes. Then came Nat-chan's graduation. What did he write for his 700th and final menu? This program depicts the casual life of a single-parent family, and one father's loving bento boxes with humorous and emotional menus.
