Felix cultivated that something very carefully, but for the entirety of their friendship, Remus had hardly seemed to notice it. Indeed, Felix had nearly begun to suspect Remus might be straight or asexual. (It did not occur to him that his friend simply might not find him alluring.)

But this was a side of Remus that Felix had never witnessed... and it was fascinating. Felix leaned in as if he could catch these coy little flirtations on his tongue like snowflakes, for he considered them as rare and fleeting. His strange eyes lit, focusing in on Remus like a kitten with a new toy. "We've met. His taste is impeccable," Felix murmured, his gaze slithering down Remus' outfit, and his body, with that same intimately focused attention. "... and has improved since the last time we spoke, when he was your friend."
