Luna Moore meets Sherlock Holmes at Irene Adler's home, then proceeds to move into 221c Baker Street. She's a photographer whose flat also doubles as her studio and her very existence seems to mildly annoy Sherlock, yet he's forced to practically live with her. This encourages him to find out more about her, but it's hard considering he struggles to read her. Slowly, Sherlock realises there's more to the woman than meets the eye, she seems to have a façade that he can't break. But, once he does...he wishes he'd done it sooner. Sherlock Holmes x OC Based off the BBC show.
