Sun & Moon Duo

It's Jeon Jungkook and Park Jimin, Jungkook being the sun and Jimin being the moon. If you think anyone else is the Sun & Moon duo you must be tripping.

K-Army call them Sun & Moon duo
BH editors also call them the Sun & Moon duo (See RUN BTS episode 142)

Have you watched Black Swan's performance in MMA 2020? Yeah, you'll see the Sun & Moon Duo there too.
