When November receives an invitation from her high school friend, Yuri, to come visit her in Tokyo, she doesn't hesitate to accept. Leaving her quiet Icelandic home for a huge metropolis would be concerning if she didn't have absolute faith in Yuri, a faith that has somehow lasted through two years of separation and Skype calls ... two years during which anything could have happened to change them both. But unbeknownst to Novi, something rather questionable is happening behind the wealthy façade of the Four Clovers Hotel, where Yuri has made a name for herself. As the CEO, she has gathered around her four unlikely friends - an arrogant millionaire, a cold businessman, a flirtatious thief and an 'angelic' artist - who are unfailingly loyal to her. And they are all connected with the mafia. The last thing Yuri wants is to bring her friend into the world of 'unofficial business' that has now become hers. But when a famous jewel is stolen at the Four Clovers' auction, and Novi becomes a suspect, things get a little more complicated than any of them had bargained for.
