The Unsolved(Sundrop/Moondrop x reader)

River is a very ambitious undercover detective and quite frankly, very good at their job. When a mysterious note shows up one day at their door containing a request, and a very bone chilling one at that, their career takes a different path. They want River to look into the secrets behind Fazbear Entertainment and expose them for their "supposed" crimes. Even more bone chilling, this mysterious person also somehow seems to know about River's past with Fazbear's, when even River themselves doesn't remember much of it, and their time there as a security guard is known by little to no one. River is forced to dig into the secrets behind the foul company and ends up learning things from their past as well, memories that had been deeply buried and long forgotten.
