On September 30, Instiz announced that DAY6’s track "HAPPY" has achieved a perfect all-kill! 

"HAPPY" topped both Instiz's weekly and real-time iCharts, and it dominated the music charts on Melon, Genie, YouTube, FLO, VIBE, and Bugs. This milestone marks the band’s first perfect all-kill, making it even more meaningful as they’ve recently experienced a surge in popularity since their debut in 2015.

Congratulations to DAY6! If you haven’t seen it yet, make sure to check out the "HAPPY" music video below.
