?It was Woosang's birthday on June 1st, and AA celebrated by uploading an adorable video!

The video is a compilation of photos showing Woosang's growth since he was a little baby. Of course, it also has plenty of model photos and BTS photos of the boys just fooling around with each other giving us more insight into their upbeat personalities!

Take a look at the video above. Happy birthday, Woosang!
