I was in section 7, and was surprised at how close I was to the stage, so right from the beginning it was better than expected. The staff were very helpful and friendly, and the fans were awesome… but I expected that.
2PM, of course, put on an amazing show, right from the opening (Heartbeat, which was perfect). The show was about two hours and it never dragged - even when there was some issues with the power, Taecyeon, Chansung and Wooyoung came out and talked and joked with the audience. They're every bit as dorky and charming as you expect from seeing their shows and videos. There were plenty of other times when all of the members stopped to talk, too.
They played ballads and dance anthems with equal skill, and even pulled out some oldies but goodies that I didn't expect to hear but was delighted to (I Hate You, Tired of Waiting). The show felt like a huge party by the end, when they closed up with remixes of Hands Up and Go Crazy.
All in all, if you're a 2PM fan and get to see them on this tour, it's going to be the best night of your year. Also, no matter who your bias is, you're going to fall in love with Junho. It happened to me, and a ton of other people, so be warned :P
