Both of them talk about japanese traditions and also about learning the arts and there's also romancr.
Both dramas written by the same person. While they have different stories, the overall emotional feeling is a bit similar in my opinion. In both, the male leads live in lower life due to family circumstances. And on every episode, new plot twist will be revealed. The difference is that in BNNH the plot twists are more shocking/surprising, while TNH's are more subtle.
