Her performances.. I liked her initially not because of her lyrics, but her performing ability. I like her facial expressions especially when she's on the stage singing. And this is done so due to Ayu putting in her emotions while singing. Some artists just sing, but they can sound really emotionless..but Ayu is different. That's why she caught my attention initially, and then after I find out more about her and realise she does composing and so on, my love for her music grew further.
I am really proud to be an Ayu fan! I think all of us here are!
