It really takes a lot of courage to hold a concert when your voice is almost gone. Maybe it takes more courage to cancel it
Anyway, i'm grateful for all the effort ayu puts in and i'm glad she managed to pull through in the end. Some observations though, from the sound of her singing, she uses her throat to sing a lot which is no wonder her voice deteriorates after a few lives. People practise a lot in the choir but their voices don't get affected because they use their diaphragm. Think ayu should pick up some techniques.
