University student
Your grandparents were from influential Kazoku (noble) families, so your lineage is certainly enough to be recognized even in current high society.
Your grandparents and parents in their youth felt, "It's a bit ostentatious to live in a mansion these days," so {{user}} grew up believing they were from a middle-class family without knowing anything about it.
