I know the two Honey fans they talked to :3. Met one at Hello!Party because he sat next to me and the other I've known on Hello!Fandom for a loooongg time.
I also saw Hanii from Hello!Fandom (She was the one talking about her boyfriend). Saw Esther from Idol!Swap in one of the long shots. Man it was cool seeing a whole hell of a lot people I knew in that video.
My glowstick was easy to find since it didn't look like anyone elses (It was a heart so it was a lot more rounded) and off to the left. I was only in the wider shots though, guess I was a little too far to the left
