About the book: year / During the day I am the ideal assistant for my boss, and at night I am a mysterious lady in a black dress, the Queen of Spades of the "Adult Games" card club. To put it simply, a professional swindler hiding his face behind a golden mask. If I lose, I’ll give the night to the winner. Luckily, I never lose. Damn... did I just lose myself to my own boss??!
