Oh god yes, she was.
Before I saw the show I kind of liked Komu, yes, but not more.
But then it was my first show to see live... and in the end I went to see it not less than four times, and god, I cried when seeing it the last time.

And while I am an absolute Kaname nerd today, back then I only though 'Who is that girl therre who is only on stage to hold Komu's jacket?'
