SF9 is now 600 days old.
The boys are a 9-member group that debuted on October 5th, 2016. They're the winners of FNC Entertainment's trainee survival show 'd.o.b' and have come a long way since their Neoz School days. They've been keeping busy since their debut, releasing "Fanfare", "Roar", "Easy Love", "O Sole Mio", and most recently "Mamma Mia" while also promoting in Japan.
To celebrate their 600 days, the boys released 5 never-seen-before behind clips from when they were teasing for 'Mamma Mia'. Check them all out below.
