While studying abroad in Russia, Lily was scouted by her husband, Shinichi, who was visiting for business, and decided to work together. As she learned Japanese from Shinichi, the distance between the two narrowed and they got married. Three years later, she lived happily ever after, but one day her husband was deceived by her friend, who was her business partner, and she ended up in a large amount of debt. For her husband's sake, Lily decides to work as a secretary at Abe's company. However, in order to make up for her husband's debts, she has no choice but to accept her ``secretary for her mistress'', which is also her physical relationship presented by Abe.
