Such coincidence!!! My lecturer for Japanese Mass Media class actually showed ayu CMs a couple of weeks ago too!!! She showed us a Kose one (the one where she's sitting on the moon with Naturally remix playing), and the 2 ones she did for mister donut.

It was totally nostalgic seeing young cute ayu!!!
ps: The Naturally remix was named the "dolly remix" and this CM is promoting the Kose Vissee dolly make-up line. I just realized this lol!! Did they name the song after the make-up line? Like what happened with Sweet mag and sweet season.
