It's interesting to think about the idea of a happy family for Maomao. But honestly, I've wondered about this before. After all, Maomao only learned medicine from her uncle because he was worried about her future. To keep her from ending up working in a brothel, he decided to teach her medicine. But what if Lakan and Maomao's mom had just gotten married normally? Maomao might not have learned medicine from her uncle and could have lived a more "princess-like" life. Another possibility (and here comes a small spoiler from the light novels, so heads up!) is that Maomao could have discovered her uncle's small library at the La clan's house and gotten into medicine on her own.
