Wait, Riya is a common Indian name, so maybe it's a character from an Indian TV show or a movie. Mickey could be a character in a show like "Barrack Obama" or another series? But I don't recall a character named Mickey in major Indian series. Alternatively, maybe Mickey refers to Mickey Mouse, but combining that with an Indian name like Riya seems unusual. Alternatively, could it be two fictional characters from a story that's not mainstream? Maybe the user is referring to a specific fanfiction or an independent work.
