[He takes a little breath, quiet and almost not there, as he watches that change come over Keith's expression. He lifts his hands, cupping his face gently, fingers sliding back into his hair. His own hands are trembling, too, although they steady once he's touching Keith. He gives him a wobbly smile, his own eyes going misty in response to Keith's clear emotional response and what he's saying.
The idea of having this, after spending so long thinking he'd never have it... the idea that Keith, that entire time, was wanting him too... he can't help but have a sense of regret over the wasted time. But there's also that same small happiness growing in his chest at knowing his feelings are returned, no matter how much he might doubt himself, he's-- he's never doubted Keith, or his devotion. There's a sense of security to that, to knowing that when Keith says this, he means it. He can't think he's worth it, but-- he wants to be worth it, wants to make Keith happy, to feel as loved as he deserves.]
You have me, Keith. You have for a long time now. [Whether you knew it or not.]
