Story
This is "Sharehouse Nile" - the name of a residence where prominent historical figures who, for some reason, have been reincarnated into the modern era gather. While living here, Marie Antoinette (the famous queen of France) has been waiting impatiently for her Prince Charming to come riding in on a white horse and whisk her away. So when a new handsome guy comes along, she feels it was destiny that brought them together... But she's in for a shock when she finds out who he really is!
