There are 9 volumes. I don't remember exactly, but it seems like she begins to realize her feelings for the nephew and is conflicted because of her feelings for his uncle. I wanna say she gets rejected by the uncle, but not sure. She realizes she loves the nephew more at some point. I think it ended with from the uncles point of view and he's head to their wedding, but again not sure.
Edit: I looked it up and it's a slow burn romance. She finally reveals her feelings for the nephew in the final volume. It was still pretty good. I'd like to see it finished.
