This is a nickname given to Jimin and
Jeongguk, two members of the biggest boy band in the world, BTS. It was given to them by their fanbase in Korea, and in
hangul, it is, 해달즈. While Jimin is the moon, Jeongguk is the sun. There is also a double meaning to the hangul, 해달, which means that they resemble
otters. Coincidentally, in
BTS's 2020 MMA performance, the Black Swan performance began with a sun and moon turning into an eclipse. Jimin and Jungkook danced beautifully together and even added a pas de
deux within the choreography. Generally, males and females dance the pas de deux together, so Jimin and Jeongguk broke the gender norms.
