A rep from 'Rebecca' stated, "The 'I' role controls the flow of acting, and the singing is very difficult so we have always had a difficult time casting the role. However, we were sincerely surprised by Luna's audition attitude, singing ability, and even her acting."

The musical will play from August 10 to November 12.
