[It hurts both he and Yuuki much in the same way. (You've been nicer to us than anyone ever has.)— he can't even begin to imagine all of what they've possibly been through. It can't be strictly from what Yuu has already told him about in regards to his family, or what Mika was put through, as well.
He's glad, though. Also like Yuuki. Now that the information has been let out, there's less tension in the air. However he doesn't fully expect for the boys to simply return to how things were on the day they arrived.]
Why do we care so much. . .?
[Zero slightly frowns as he considers the question. Maybe there isn't much of a reason at all.]
Kids should be able to be kids. You deserve to be happy, to be cared for, and treated kindly. [he pauses again in simply recalling the past.] Or maybe, for me, I've been thinking a lot of my brother around your age and earlier on. And that I've been thinking of when I was that age as well.
[There's so much that Ichiru had gone through. Yet altogether, there's no way to compare the life his twin had, and that with Yuu and Mika have experienced.
He lets out a silent breath.]
It's just as Yuuki says, though. Ask us anything at all that you want to know, be it now, or whatever may come to mind at any point. We promise to give you nothing but the truth.
