In "Damsel in the Red Dress" Alicia usually describes her feelings for Kattar as fire or burning. This is both because the feelings are intense, but also because they're almost insufferable. She doesn't want to have feelings for him, so they are painful and unpleasant.
From Kattar's side, we don't get to hear his narration, only see his reactions, but we do get to see a couple of teasers, they aren't very unclear, because, interestingly enough, Alicia knows that Kattar likes her, and is just trying to ignore it, she can divine his reactions for what they are, even though they are subtle.

I come forward anyway and sit down on the couch beside his chair. I catch the moment when he notices the scent of spices - try to hold onto the sudden change in his color and expression - as it slips through my fingers like steam, and he relapses into his heavy sadness - heavier still if that’s even possible, and darker.
“You put on perfume-?” It’s an accusation instead of a question, still, I smile painfully, hoping to pull him out of his shell.
