I know I'm really late on this one, but Chernyshevsky's What Is to Be Done? is said by many to be the book that most sparked the 1917 revolution, and it's about love. Vera is living in kind of an oppressive family that want her to marry well, and befriends her brother's tutor, who tries to help her escape. The novel is about the importance of equality in a relationship for true love, as well as more obliquely (due to censorship) about the need for economic equality for a thriving society.
If romance isn't crucial, but you want a breezy but clever book about revolution/decolonization with a bit of a Hogwarts-y vibe (in the least transphobic, most positive sense), RF Kuang's Babel is fun.
