But doesn't that inherently mean she doesn't understand what love and friendliness actually is? She knows what she thought was affection, but the first time she experienced it genuinely, it was from Adlet.

She knows what insincere, fake affection looks like.

That's why Hans is getting confused. She's showing friendliness that he reads as false, because that's the only kind of affection Flamie knows.

This makes my brain hurt.
