“It was about five years ago when I watched 2PM’s concert and I was like ‘I want to be like them someday,’” said Junior in a press conference an hour before the concert. “And now I am performing onstage in the solo concert. How amazing.”

“It’s like a dream come true to us who watched senior boy groups.” Yugyeom and Mark said. “Thanks to fans’ support, we made it.”

The group had won major programs including KBS 2TV’s “Music Bank,” Mnet‘s “M! Countdown,” SBS MTV’s “The Show,” with “Fly,” title track of their latest album “Flight Log: Departure” released on March 21.

It was also their first exclusive concert, which allowed them to divide themselves into two and impersonate girl groups to perform GFriend’s “Me Gustas Tu” and Red Velvet’s “Dumb Dumb.”

“I thought fans would enjoy our flip side.” said Bambam. “(The exclusive concert) is an opportunity.”

“Our next goal is to be a long-running boy group,” Jackson and Yugyeom said.

“We are told GOT7 is improving as time passes,” said Junior, when asked whether their first victory in a music program came later than expected. “I don’t see this as a late win. I would rather say we have improved, compared to our debut stage.”

The band will soon embark on a world tour including China, Japan, Thailand, Singapore and the United States,.

Members expect a lot from the international tour.

“I was impressed and surprised when fans welcome the band at the airport,” said Junior, a stage name used by Park Jin-young. “This motivates me to learn a foreign language.”
