HYBE Labels x KOZ Entertainment boy group BOYNEXTDOOR is gearing up for a September comeback, according to media outlet reports on July 13 KST.

The rookie boy group will be returning with their first official comeback since their debut, just 4 months after the release of their first single album 'WHO!' in May. 

A 6-member boy group made up of Jaehyun, Sungho, Riwoo, Taesan, Leehan, and Woonhak, BOYNEXTDOOR made their mark on the K-Pop scene with triple debut title tracks "But I Like You", "One and Only", and "Serenade". 

Meanwhile, a ferocious rookie competition is shaping up for this coming September, with SM Entertainment's new 7-member boy group currently aiming for an early September debut, followed by YG Entertainment's 7-member rookie girl group Baby Monster also scheduled to make their entry some time in the same month.
