Couldn't I ask you the same thing? [Yuya stares up at the ceiling as well.]

... I met Gongenzaka when I was nine. Before then, I didn't really have any friends. And then I hurt him so badly, and since then it's just--I'm always failing. Because I love them, I want to give them my best, but what good is that? When they say they're my friend, I don't really know why. Other people are nicer than me, and smarter, and better at what they do. So why choose me?

[Why not someone who's less of a failure? He's too selfish to let go, but he doesn't understand it.]
