There is literally no reason to dislike it. Even if you're not a fan. Granted it might just be me, but I rarely hit the like button, much less the dislike button. But what's to dislike? The PV is nice, and the song is nice too. I am pretty sure it's some sort of anti-campaign, and I have no idea who the antis would be in this case, as I haven't seen anything about antis and STU48 yet.
Well, I hit the like button...
Someone wrote this though:
公道を逆走するな、法律守れ的なコメントを見たのからかな?自転車で走るシーンのカットが変わってる!
So did anybody save the original upload or is it available somewhere else, such as dailymotion? Seems to indicate that there was a chance in the PV involving a bicycle scene.
