King of Spades

I’m not sure what to call this, maybe it’s a fanfic (I don’t really know, but my understanding of such things is that it is…if not feel free to correct me) not super good with tagging stuff but I will try my best, to think of and use appropriate tags.
This story features Eisuke Ichinomya from the Voltage game Kissed By The Baddest Bidder, however let’s pretend that the main character was never put up on auction, but instead meets Eisuke in some other way, and let’s further pretend that she works in a clothing shop located inside the hotel, not as a maid. Okay?
P.s.
I don’t have regular access to a working computer with Internet so I’m typing this on my iPad/ phone if that makes any kind of difference in how easy this is to read. Also I don't own Eisuke Ichinomya, I don't own Caroline or any of the other voltage inc characters ( as I write this if and when I use them I will try to remember to add them to the list. )
