all kids go to the school apparently. And I believe Cassandra Goth was in the LIvestream. What I'm not sure about is the crushes and autonomous asking out system, I hope it's coming to base game for people who aren't able to get the expansion.
I noticed some things in the livestream that resembled my high school experience. But I was the Socially awkward bookworm who hid in the library a lot lol.
I restarted one of my favorite families I liked playing as. The kids are child life stage and I have it set to long age cycle, so I can get more time in before I am able to get High School Years, and then I may age them up early if they aren't close to the correct age once I'm finally able to get the Expansion.
