[It's evident from Fai's face that he wasn't prepared for that question at all, and for a moment he just stares at him in incomprehension. Then he slowly shakes his head, not in answer as much as confusion.] It's a bit like asking someone if it's nice to have legs when they've never been without, I think. I mean, I can't even imagine life without Yuui, and I couldn't live without him, but... if I hadn't been born a twin, perhaps I would've felt differently? But I'm not sure I would be me either.

[He shrugs a bit awkwardly.] And yes, I think so. If there's been anyone who wasn't, it's probably been hushed up. [Welcome to Fai's family's wonderful "standards", Armin.]

I can understand wanting to keep you safe, it must've been hard for you. But... wasn't it a bit lonely too?
