ryujin was born into a wealthy and well known family of doctors. since she's young her parents tell her about how mr hugh baclk helped them out and how she should always be grateful to the man she has never seen in person. she doesn't know why though, she only knows that because of him her parents own a couple clinics in and out the city. because of their long history of doctors in the family, ryujin was put into a medical degree without being questioned if she ever wanted such thing. in fact, her true passion is arts, specially dancing. in exchange for her to study her parents allow her to take dance classes, which she does since she's young. by now she even became a part time dance teacher – doing it for free and passion, as she doesn't need an income considering how rich her parents are. as long as she does well in her degree, her parents don't mind giving her money but they are rather controlling to the point of having a fellow male medical student signed up as her potential future husband – the only idea that ryujin hates and fights against the most.
ryujin is a friendly girl, despite the distress of studying something she hates and having one foot in a potential arranged marriage, she manages to be a bright person. she hides one secret – until she came to the manor, she used to have a girlfriend. ryujin leans both ways, which would get her probably grounded for the rest of her life if her parents ever knew, and the marriage would probably be sealed off. and that's why she's here. along with her invitation some pictures of her with her ex girlfriend tagged along.
