Never underestimate the power of loyal fans, especially when it comes to buying tickets to an upcoming show. That's the lesson learned this week as fans of BigHit Entertainment's ever-popular boy group, BTS, crashed servers in a desperate clamor to purchase tickets to the group's upcoming concert.

On September 16, reservation tickets for BTS' "The Most Beautiful Moments in Life, Part 2" concert went on sale. As the clock struck 8pm KST, servers were slammed by a flood of eager fans and, unable to keep up, several crashed.

Despite the setback, tickets for all three nights of "The Most Beautiful Moments in Life, Part 2" concert series sold out, proving the popularity of this dynamic septuplet.

September has been an exciting month for fans of BTS as the group surprised everyone with the release of their dramatic and beautiful "on stage: prologue" video. While the video was enough in and of itself to thrill fans, the announcement that came at the end is what really got fans excited as the group promised to make a comeback this October with "The Most Beautiful Moments in Life, Pt. 2."

Toting the name of BTS' highly anticipated comeback, November's concert comes as a follow-up to the group's "Episode II: The Red Bullet" concert tour which took place earlier this year. "The Most Beautiful Moments in Live, Part 2" series of concerts is to be held at Olympic Park's SK Handball Arena in Seoul, November 27 - 29.
