Bangtan Sonyeondan aka BTS made their debut in 2013
They work so hard and there were times when they were awake for two to three days for practice
They started with 35 fans from South Korea
They knocked on each and every door in America and asked them to attend their concert which was free
And now they are the biggest K-pop band in the world
BTS enjoy incredible fan following called as ARMY
They always worked hard and promised their fans to come up with something new always
Wishing BTS, a happy 9 and many more to go
