Last year I went to the 29th with one of my close friends, then I went to the 31st alone. And I have to say, even though I had an amazing time at both concerts, it was a little bit more fun on the 29th being with someone else. On the 31st I sat next to this single Japanese man who was about 40, and he wouldn't stop screaming AYU!!! at every chance he got. I wanted to yell at him but I didn't want to be rude...
