虹 by Aqua Timez for ごくせん3

I got sick of Korean so here I am, posting about my favourite song of the moment. I haven't even watched G3 yet! It gives me the very jumpy feeling. The lyric is beautiful and the whole song suits the whole Gokusen theme, just as V6's Feel Your Breeze and D51's No More Cries did.
