"5x10" is a new song that's been created to go along with the 10 year anniversary of their debut, and the tour that comes along with it. Nino was in charge of the lyrics.

I only gathered together the words that the other members sent me. But I thought of some things myself, too. I wanted to make it something that the more you listen, the more you discover, that when you sing and when you look at it, it hits you. One thing I definitely wanted to put in was "We'll be five, forever here." With the five of us standing onstage and singing that line, I thought that people would be moved beyond reason. Because we've always been five, right? Not six. (smiling)

Dawwwww, nino-ie.. ie.? yeah it doesn't work when you add korean suffixes to the end of japanese names
