I think it's really good/nice. It reminds me of 'Who...' in the beginning but I have to say it's MUCH MUCH better than 'Who...', which I never really cared for. Her voice still sounds like it's going down the drain but she makes up for it by supporting her vocals with a lot of emotion. The song is very sorrowful but that's why I like it. The more I listen to it the more it grows on me which is a good thing. It's an Ayu classic
