Sometimes the fanfiction Categories might include a code you don't know what it means. Maybe you'll find an explanation here. If not, ask me and I'll add it to the list.
A = Adult (see story ratings)
M = Mature (see story ratings)
MM = Michael & Maria
POV = Point of View (the story is written from the POV of a certain character)
PWP = Porn Without Plot (the story is mainly just smut for smuts sake, no plot needed, nor are clothes ;) )
T = Teen (see story ratings)
YT = Young Teen (see story ratings)
