[Probably no surprise that's the first thing out of Keith's mouth, after letting Shiro articulate himself for a moment there, understanding how much it can take to try to put this all into words. But he means it so much - just as he can feel how much Shiro means it as well, when it comes to Keith. They both value each other's happiness so much above anything else.
But Keith isn't without his selfishness either, and if he's honest, now that he's had this taste of what it's like, with Shiro? He's not sure he could let go of it so easily. Something a little more serious settles into his expression as he looks to him, perhaps vulnerable too despite himself as he speaks softly. Resolute.]
We can have that. [Can't they? Maybe it's one thing to touch and kiss out here in the moment as they pour out their emotions like this, light and dark mingling around them. Another thing is to choose how they'll continue from here on. There's still so much to say. His own brazen want almost mimics confidence.] If you want this too, if we're both...
This - [He's squeezing the hand Shiro rests over his heart again.] This is the happiness I want. That I know I can give you.
