Her son, Mokoyoshi, has recently become obsessed with "cooking," and Kumi is happy to see Mokoyoshi, who has never shown interest in anything, earnestly gripping a frying pan. However, there is one problem... Mokoyoshi uses a large amount of "olive oil" for cooking, which puts pressure on the household budget. Kumi complains about the clearly outrageous consumption of olive oil, but... One day, Kumi carelessly spilled olive oil on her big butt!
