That's the "bad news" part of harem VNs with lots of girls: they have to be rotated and you miss out on your favorites, often for multiple updates.
TropecitaGames could always do bigger updates with more girls, but then everyone would complain that it took way too long in between. Considering how large the "class" is eventually expected to be, probably best to find enjoyment in every girl available, then absolutely cherish the releases that have your favorite involved. By playing all the releases, especially the ones where someone new is introduced, maybe you find someone you look forward to as much as, or nearly as much as, Maddie. If Trop decides to bring in another girl with Dom tendencies, maybe you get to be the meat in a Maddie/newgirl "sub sandwich".
