Though Idk what should be different here except the PV being shorter.
Basically just some easy promo for the song.

A better shot of the new JAPONESQUE shirt from the rehearsals today:
Interesting thing she says is, that she posts so many close-ups from the rehearsals, cause she wanna surprise us. Or else she'd reveal too much.
