Yutaka, Minoru, and Tane plan to go to the zoo on the weekend. Yutaka was asked to make a bento with octopus sausages for Tane, but in fact, he only specializes in rice balls and has never made a bento before... Therefore, Yutaka asks his work colleague, Ohata Rei, to practice making a bento box. On the morning of that day, they finally go to the zoo, but when the three are about to head to the zoo, it suddenly starts to rain. Yutaka came up with something for the downing mood Tane.
