Everything that he sees in Shiro's expression just does so much to the way his heart clenches in answer, the way he returns his gaze - loving, and something like longing too.]
I love you, too. I... [There's only the slightest moment where he pauses, tentatively, before he shifts the hand on Shiro's face more and leans in, kisses him gently, but a show of that emotion, an action just as much as the words.] Always, Shiro.
You mean everything to me. You're always - you've always been everything.
