Given how fast
other paths are closed in Ch. 4 once you choose one, I wouldn't be surprised. In terms of LIs, you can already get what you want including the harem, or at least everything but a pure Valeria path because I can't find a way not to be
blocked by her at the end, when you say you love her during the last sex scene (either I'm doing something wrong or it's not possible at all
).
Anyway, given how this chapter ends, having 1 or 2 chapters focused on the story and a final one with the endings would make sense. So 6 or 7 chapters look reasonable.
