I think Hana doesn't love Miyako in particular. She feels sorry for her, yes. She loves her food, yes. But compared to Matsumoto, there's nothing really going on on Hana's side. It probably can't end like Majo to Houki to Kurobuchi Megane.
This sounds like it's fairly early on in their support. From what I recall, Hinoka and Camilla stop calling each other "Princess" at the start of their B support.
