[Action!]
[Tsuna watches him leave with a faint smile, glad he hadn't been called an idiot - in so many words at least. He's about to begin playing with Daisy again when a singing voice catches and holds his attention.

Akito's voice is beautiful, Tsuna mesmerized by it. He'd had a feeling the other would be a good singer, just because his speaking voice is so sweet and adorable on its own, but he's completely blown away, and can't, won't, doesn't want to do anything but sit and listen for a very long time]
