Problem is - he's already fucking Anne and that one was the climax of BB
It's just rushed, like he got scared he's losing patrons or something, really nothing close to BB it terms of "storytelling", just scenes thrown around at random
Here's my guess on this topic. Total speculation. As I recall, Big Brother Another Story pulled ahead of Glamour for a short time in the fucking department, with Max having sex with Kira in BBAS before Max got there with Kira in Glamour. If I were DS, it would piss me off to lag behind a clone of my own game. (Side note: No disrespect to BBAS - I love that game too.) Shortly after BBAS allowed Max to fuck Kira, DS added that part to the Glamour story as well. Then shortly after that, DS one-up'd BBAS by including Lisa, and now Ann.
My guess is that DS really doesn't like being behind the clone of his own work. So what's the best way to leverage his own creation, distinguish it from the clones, and take his reboot in a direction no one else can follow (not without a ton of effort)? My guess is that DS wants to tie up the Villa conquests and then have Max go to college ASAP. That way he can launch his BB story in a direction (into a larger world) that nobody else can copy -- not for a while anyway. Not only that, but with Max and Kate freely moving around all the same locations, it allows him to reuse pieces of one story in the other, reuse images, and this allows him to keep releasing "the biggest update so far!!!" (we know how he loves that shit).
I'm not saying this plan is the best plan (or worst plan) for the game, I'm just saying I think that's where DS is headed, and he wants to get there quickly. That's why the Villa stuff happened much faster in this version.
Personally, I like it. I like the Max side AND the Kate side, and I like when the stories mix. So if this is what DS is doing, I'm a fan. But I also realize half the population of the fanbase is pissed. To each their own.
