Oh, and here's another performance by Ryosuke. This perf is the one that got me interested in him in the first place. His voice is higher than in the Asia no Yoru perf, but it's still cute! ^_^ The other guy in this is Yuto Nakajima (another cutie). This is one of my favorite songs, too. It's on my playlist 3 times!
