Yes, Ady is the female lead.
She was alright in The Outsiders. The character wasn't that likeable but I thought Ady's acting in there was really good and natural considering that she was still relatively new to acting at that time.
I'm the opposite I've always found Liu Xue Hua to have very fierce and cold-looking eyes. She played a rather good wicked witch role of Empress Lu in "Miracle Healers".
