2PM continued to thank fans for the long wait by treating them to their mini concert, '2PM Is Back with Genie', which many of you may have watched live through YouTube!

3,000 fans crowded around the M-Stage in Gangnam on Friday, the 17th at 9PM KST to watch the return of the 'beastly idols'. 2PM let fans know that they're back for good by opening the concert with "I'll Be Back", and then pumped up the mood by performing past fan-favorites, "Again And Again", "Heartbeat", and more.

Before wrapping things up, they also made sure to perform their double title tracks "Come Back When You Hear This Song" and "All Day I Think of You" ("A.D.T.O.Y."), and ended the concert with a bang by getting everyone's hands in the air for their hit song "Hands Up".

2PM shared, "We had such a great time because more people than we expected came and enjoyed our concert with us, and we thank you once again to all of the fans who stayed with us until late at night. With so many cheering us on, we will work harder and continue with more activities. Thank you."
