Someone certainly knew how to flatter. The raven-haired youth shrugged awkwardly, unsure of how to respond to such kind of affection. It's not like he's received affection before, though the sudden amount from strangers was quite strange, really. He didn't question it, however, as this man seemed friendly and polite. "There's not much to be curious about, Kaworu. . . Although, it's really nice of you to say that, so thank you!"
A cheerful laugh escaped his throat as he finished adjusting himself on the seat next to his possible new friend. Ah, he seemed to find ease in befriending others, didn't he? The boy could recall a time where he was unable to speak to others so freely; what a dark time that was, but he still overcame it.
With that same smile printed on his face, Seto watched as Kaworu began flipping through the pages of sheet music. Each song seemed so pretty, and his interest was only increasing as he pondered what kind of song the other intended to play. Surely, after the recent song he heard, it was to be a spectacular melody. Such a talented pianist can't possibly disappoint him.
"This instrument was tailored for your kind.."
'Your kind'? What could Kaworu mean by that--? No, it was quite obvious, yet it confused him. He'd assumed the man was human, but of course, he was only judging by appearance. . . His personality seemed to make much more sense now.
Despite realizing what Kaworu had meant by that, Seto chose not to mention it. After all, he wasn't much different from him, was he? He was human, but different. Everyone was different in their own way, and the youth never wanted to judge someone for their differences.
"I sure hope they will." He positioned his fingers atop the keys, prepared for whatever song Kaworu had in mind for him. "The piano was such an amazing invention. Out of curiosity, do you have an interest for any other instruments? You seem to have a talent for music." Seto himself loved music, especially the soft classical tunes that would lull him to sleep as he enjoyed the time he had out in the forest.
