I really like the small touches of historical realism, like the mention of famine, the simple dowry system, and the hierarchical family structure. The second branch, the first branch, the grandparents—all living under one roof, with clear pecking orders. The way the grandmother makes financial decisions based on favoritism feels authentic to many traditional families. It's not overly explained, but you pick it up through actions and dialogue. The author trusts the reader to understand without long info dumps, which I appreciate.
