Are the people who went to the concert feeling okay?

I was looking at Astro concert reviews and what is this picture?
I can't describe in words the feeling of seeing something sacred and tremendous.

There must be some of you who have seen it two days in a row. Is your heart okay?
My heart hurts just looking at the picture lol

I'm seriously jealous of those who have actually seen it
It must have been a truly happy time

[All] Are the people who went to the concert feeling okay?
