All caught up now so time for my thoughts if your interested.
Short version:
Really
expletive enjoyed this story and characters so far. Subbed and cant wait for more.
Long version:
I
always appreciate these breakdowns of what folks liked, especially where the characters are involved, and the criticisms (they sometimes help make my game better, as seen with the extensive amount of QoL overhaul compared to the early builds). Thank you for your kind words! <3
No real difference, and you pretty much nailed it on the head. I've actually been on the fence about making the distinction more clear, as all of the girls (and bros) are important to the overall story as a whole.
That said, some may move between the two depending on story circumstances as it progresses. I haven't decided on anything in that department as of yet.
