[Leans into the hug, nodding slowly in a way that Shiro probably feels more than sees, Keith's other arm wrapping around him in turn, though his hand stays where it is at his face.]
I love you. [He breathes it out again in affirmation and even then it sounds like a confession still somehow - something he's literally never said to anyone in this way, spilling over with that want again. Maybe he can't take away Shiro's uncertainties as easily as he wishes he could but fuck if he won't make sure he knows he's loved anyway. That was always the goal, even when he couldn't say it in the full depth of how he means it. Now... he can, and will.]
