I'm specifically interested in the Harem tag. I'm busy writing a series. I know the beginning, middle and end of the first book in a broad sense. The MC only ends up with a single character by the end, but the first three chapters give an impression that the series might be a harem. There is an important reason for this. What I'm worried about is that when I start publishing to RR that people will read the first three chapters and get turned off because I didn't use the tag or get to the end of the first book and then get pissed off that it obviously isn't a harem when I used the tag. What is the best way to approach this to avoid alienating potential readers?
