It's SG wannabe

I went to a concert yesterday.
This concert title was "It's SG wannabe".

Do you know SG wannabe?
SG wannabe is best vocalist singer that be consist of three members(Lee Seok Hoon, Kim Yong Jun and Kim Jin Ho).
I'm Seok Hoon's fan.
Of course I like SG wannabe's songs.
Nowadays I was very tired because of so many homeworks.
But I could enjoy happily during the concert.
They sang so many songs.
That time was very fantastic.
I wanted not to finish this concert.
After finishing this concert, I didn't want to go back.
I was satisfied with this SG wannabe concert.
I really want to go to the concert again.
