Happy birthday to B2ST's maknae, Dongwoon! �Despite his mature appearance and nice height, he is still the youngest of the group.

Born on June 6, 1991, he has now turned 24 years old internationally and 25 in South Korea. �To celebrate, it appears B2St got together for a mini birthday party with him and others as you can hear men and women alike making excited sounds in the video posted below by Doojoon onto his Instagram.

He blew the candles, probably feeling all the love, and posed cutely with the cake. Doojoon asks, "Who's birthday is next?" �Do you know the answer?

Happy birthday again, Dongwoon!
