No it's not, he wants to tell her. That's not enough at all. They both know he'll leave her again eventually. He'll hurt her and she'll hurt him, and the worst part about it all is it isn't something Karkat can control. The state of the world they live in is out of their hands; what they have now, however screwed up and painful, is the best either of them are able to do. It's not enough.

He doesn't say any of this, though. Merely shivers at the sensation of her fingers brushing against his scalp, her breath against his ear. Deprived of physical contact that wasn't pain for so long as he has been, the reaction he has to the simple touch and affection is almost overwhelming. He doesn't know how to react to it.

He lets out a sigh and pulls back from their embrace -- not by much, mind. Just enough that he is able to look her in the face again, take in the pallor of her face, the tears that cling to her lashes and glisten in streaks down her face, the pull of her brows and curve of her mouth, the shift in expressions. Refreshing everything he'd missed, recoloring his memory. For a while, that's all he does; look at her.

It's gentle and almost hesitant, when he finally leans in to press his lips to hers.
