We Cannot Pay You for This! Ms. Morikawa of Accounting Department

Sanako Moriwaka, 27 years old, single. She's been dedicated to accounting since joining the company. Diligent work and a fair salary. She seemed to be living a perfect life, neither too much nor too little. Recently, however, a colleague who showed no signs of having a boyfriend has found one, leaving her a little confused. One day, Taiyo Yamada, the ace of the sales department, brings in a receipt for "4800 yen, takoyaki." Does accounting offer a glimpse into the inner workings of the company?
