I'd be surprised if the dev isn't working on that. It's just, for the first week of college to work, the MC's only going to run into dorm-mates, RAs, and a few others (plus the parents and sexsister).
So with the foundational characters established, the dev can now work on extra layers like hot teachers, hot librarians, hot classmates from electives, hot sorority girls, frat boys/femboys, hot college medical staff, hot college athletes, hot stoners, hot CEOs running internships, and hot senators and their hot assistants coming to give hot talks.
