"Rangeen Kahaniyan" sounds like a series or a show, probably an Indian TV series or web series. The numbers and abbreviations like S15 (Season 15), E0104 (Episode 0104) suggest they're looking for a specific episode. The mention of Alt Balaji makes me think it's related to that platform. However, Alt Balaji is a known Indian streaming service, so maybe "Rangeen Kahaniyan" is a show available there, but the user is trying to find a specific episode for free from an unauthorized source (the "www free" part).
