I've never heard of fmg, what does it mean?
FMG stands for Female Muscle Growth. Basically, scenes where a female character gains muscle and becomes more muscular.
any chance of a fmg harem ending?
There is currently an ending featuring a FMG threesome. As for a full-fledged FMG harem, that's unlikely. Given how the harem routes are developing, I can't fit a FMG harem ending into the story.
