Fans of BTOB were certainly eager to see the group perform live.

The seven-member K-pop boy band held their Born to Beat Time concert on Dec. 19 and 20 at the Jangchung Gymnaisum in Seoul and they couldn't have been more excited to perform for their fans.

When tickets for the performances went on sale, all 2,000 seats for each performance were sold out within five minutes of going on sale. At a press conference before the show this past weekend, the members discussed their reactions to the outpouring of love from their fans.

"At that time, I was abroad," explained Seo Eunkwang. "At first, I didn't believe it. I asked whether it was a lie again and again."

"I like it a lot," Jung Ilhoon added. "Really. I screamed to the point where I was so loud that the waiting room was flooded with my voice."

Born to Beat Time was BTOB's second solo concert since their debut in 2012, following the 2014 Hello Melody in Seoul performance and follow up show in Busan.

In June, BTOB released their first full length studio album Complete, which featured the title song "It's Okay."
