September 1, 1997 is the day of the BTS's youngest member, Jeon Jungkook's birthday. He turned 20 today (21 in Korean age). ;_; I'm in tears. He's all grown up.

To all ARMY's we really love how our boys are growing up and succeeding in life. Praise these boy's and all the hard work they do to appreciate us all. We do love BTS.

A happy birthday to Jeon Jungkook. Who used to be an adorable, cute, hot, amazing, caring loveable nineteen year old. To an adorable, cute, hot, amazing, caring, loveable, twenty year old. We love you and all the BTS members.

I say Jin must be so proud of you, watching all his children grow up and loving life right now. Sure Jungkook was a little bit of pain for you XD (as a joke) We all know you love him deep within your heart.

Happy birthday Jungkook. And we hope you have an amazing 20th birthday. <3
