I just kind of occasionally pass through with this game and don't really follow it closely. Is Chapter 13 being the final one kind of set, or is that just speculation based on different things?
I vaguely remember how Chapter 12 left off, but IIRC the main LIs finding out about each other and having FFM, Brenna/Ophelia, etc. content basically just happened. I was really looking forward to that kind of content (especially Brenna/Ophelia stuff ever since the beginning when it was hinted at) so if there's only like 1 & 1/2 chapters worth of it that'll be kind of a letdown for me. Unless Ch 13 is just gargantuan and has a lot of that kind of stuff lol.
