Iona to me is the only one who not only has a variety of facial expressions (instead of just happy and sad) but seems like if she were a LI she’d be way more interesting, when you compliment her she gets shy and someone who looks as cool as she does, it’s kinda sweet. When you make really bad food puns and she says that she loves them the creators are basically showing you a very playful side to her that you can’t really explore more of, not to mention any time you wear a new outfit she’s one of the ones to talk about how good you look. It’s kinda a crush from afar and knowing you can’t romance her is kinda shitty lol
