The original work of Yuko Aoki's popular manga "これは経費で落ちません" is adapted into a TV series. Moriwaka Sanako (played by Mikako Tabe), a single woman working in the accounting department of a soap manufacturer, meticulously checks all receipts and invoices one by one. In the process of carefully checking the contents of the invoice, she gradually becomes aware of the troubles of people related to expenses. So one day, the ace of the sales department, Yamada Taiyo (played by Shigeoka Daiki), came with a receipt for 4,800 yen for takoyaki and asked for money. Faced with such an unreasonable invoice, she naturally fought back, but it aroused Yamada's interest in her, and the life of a woman who was not good at love and too serious changed. Others include Ito Sari, Hiroyuki Hirayama, Fukikoshi Mitsuru, Kiriyama Ren, Matsui Airi, Han Yeong-hye, Kakuda Akira, Katase Nana, Moro Moruoka and others.
