tbh, i'll be shocked....
SHOCKED...if it outsells Love yourself. not only because of the tie-in, but because come on, the 2 most popular members had solos on those too. and there were 2 CD+DVD editions. i'll honestly say it will go around like...White X'mas....or like ONE DROP.
"Going!" is not my favorite KAT-TUN song, AND DAMN IT AUTOTUNE, but somehow i like it. idk whether it's my sympathy card playing or whatever. i do think the arrangement is much easier to digest than "Love yourself". all in all though....they are both the same in many, many ways.

(i do know they are both by the same dude)
personally, drop the pop, go full-on dance music, KAT-TUN pleassseee.
