Do you remember who the man behind "Energetic" is? It's none other than Pentagon's leader, Hui! This will be the first time that Pentagon make a comeback with a song composed by one of their members. With Wanna One's "Energetic" having swept up a whopping 13 first place trophies on music shows so far, many expect Hui's newest track for Pentagon to have a notable impact. 

Furthermore, it's also been revealed that all of the tracks on Pentagon's 4th mini album were composed by the group members themselves!

Along with the release of their 4th mini album on September 6, Pentagon will be kicking off their 3rd solo concert, 'TENTASTIC Vol.3 ~PROMISE~', at the Yes24 Live Hall in Seoul. 

Get ready for Pentagon, coming your way real soon!
