Any Stories Where the Protagonist Transmigrates Along With Their Whole Class or Dorm?

I want something like Xiaosa Ge's story. It was a silly animated series, and I've forgotten the title. The story was about seven or eight people surviving in the apocalypse. They were all classmates. I haven't watched it in ages, so I don't remember clearly, but that was basically it. I want something where the protagonist transmigrates.
