Rookie girl group BILLION dropped their second MV, this time for a very fun and cute summer track, "Sallang Sallang"! �The song is sweet and super catchy as they repeat, "sallang sallang," while they go on a trip to the beach.

The girls seem to be enjoying a nice vacation as they bike around as a group, play on the beach, jump in the pool, and more. �The MV even shows additional footage from their dance practice room and car rides, showing the girls getting along like close pals as they smile and laugh along.
