I don't know...it doesn't even sound like WILL at all...just the "Zutto, Zutto" which reminds us of "Kira, Kira" in WILL...musically, not the same. We need to wait for the full version of the song....it's only 15 seconds preview, like 5% of the whole song. You guys not gonna sentence someone to jail with only just 5% evidences? Let's all wait
