I wish the concert will be rescheduled on a weekend. i myself, skipped off work just to attend and the majority of the japanese rarely do that for just a concert. but more importantly, i wish Ayu get well. She'd been working so hard since the start of the year and I can't imagine how she's feeling now, not being able to perform.
Poor ayu. Let's pray for her fast recovery. I'm 100% sure it'll be rescheduled.
