Horizon Ridge Never safe from you.

He was talking out of his ass, but being an ass meant he could be quite convincing, and she was suceptible because of her average-ness; or that's what Firefly presumed as he complimented her again and again, eager to keep her with him so that he wasn't running around in the valley alone. 

When she closed the distance between the two of them he didn't think much of it, but then she was getting closer still — brushing her nose against his chin with some hesitation. He knew he had her right where he wanted her. He smiled as she pulled back from him but didn't let her get far - reaching for her next, sliding his snout against her cheek with a small nibble, finding it easy to use his affection to win her over further. 

In short, he was a total asshole and Yami should've been running from him, not leaning in to him.
