i think jinshi, maomao, and dai lu (my oc) all have kind of a hard time showing affection, but in very different ways. maomao best shows her affection for people through acts of service, because doing things for people is what she's always been good at. jinshi i think defaults to gift giving, because he has so many resources at his disposal that he doesn't really have to think about it when he's giving someone something they want or need. dai lu, unlike the other two, is much more expressive with her words, so it's very easy for her to provide the people she loves with words of affirmation, but in almost all other respects she's pretty awkward (mostly bc of her background as a courtesan).
