Okay, now it's interesting because the game splitted in three routes with different contents for three Love Interests. Kaija for the templars, Queen Titania (MedB route) for the Elves and Fiona being neutral route (my favorite and the ideal in my opinion if you want to stand in the middle between templars and Elves)
The only one dev needs step up the content is Elea, she feels more a side character instead a main LI because she just looks like a obsessed fan of Myths and Fantasy Legends and nothing else. Unless dev is planning something for her (or maybe it's because i skipped her route lmao)
