.... how about dating all of them and see their flower events?? You'll know more about their personalities . You can decide who will you marry after that (depend on your preference). Reina and Oracle still walk to the mountains to do their job (Reina with her research and Oracle with her alchemy) after marriage so sometimes they're not home. Georgia is a fun girl, too.. in my opinion..
because the best way to know about their personalities is via date, and maybe you want to visit the daily dialogue transcription thread to see some of their dialogue viewtopic.php?f=24&t=144263
