Myoui Mina was just a fresh graduate who currently searching for work experiences by doing internship in a multinational company, P&C Garments Corporations. She thoughts everything would run well and she'll have wonderful time in such a wonderful company. but just with a month of her internship, hell is the only thing she got.

But Mina could go through the hellish days of her internship all because of her time she spent with some employee who apparently loves to slacking-off and roaming around the office freely.
