he says that he knows that japanese concerts, esp ayu, have a huge production value to it and that he wouldn't waste an opportunity to watch it. but because he didn't sleep for a couple nights, he wasn't in the mood to watch the concert, which is why he dozed off during some parts of the concert. he adds that it wasn't her fault, but instead it was his own fault.
