Navi waited for him to explain, and tried to think hard about what other things could cause warmth in a human body. Sickness, adrenaline, overexertion, nope, none of those. She caught her mind starting to wander to how pretty his eyes were, how she wondered what it would like to be kissed. She'd seen it happen before, but then she'd been a fairy. She hadn't had arms to hold someone yet, or lips to press against someone else's. But now I do.
She listened to him talk about his upcoming fight, and beamed. "You're confident. It's good in a fight, to know your ability. Do you know your opponent's weaknesses?" She didn't know if he was experienced, though she assumed as such; he had the bearing of a warrior. If there was one thing she could recognize after her adventures, it was that. She noticed his palm was still resting against her cheek and risked moving a little closer. "You're nice and warm."
