[All] They say that Blue Coral Reef is #1 on the Karaoke chart because of Hani.

The song that was performed at Hani's Tokyo Dome solo stage was 'Blue Coral Reef' by Seiko Matsuda, a representative Japanese song from the 1980s.

They say that it was their first #1 hit on the Japanese karaoke charts. New Jeans Honey's influence is amazing.

I also watched the stage and looked for old videos, but I kept looking for more.

I should try singing it at a karaoke sometime
