She knew.
It was the song that depicted her senior sister's life. Even though the images were not clear and could only be inferred based on the tone, Nan Hua had the picture of what happened to Chen Yuan based from that song.
However, the song hadn't ended yet.
There was someone from the past who could disturb her peace coming once more. Thus, Chen Yuan was determined that she would go and search for him.
She wanted a closure.
Or probably an answer?
Nan Hua was not totally sure. She cupped her fist. "Thank you for playing the song so beautifully for me, Senior Sister Chen."
"It's not only for you." Chen Yuan's eyes had closed once more. There was never any difference whether she opened or closed them as all she could see was darkness. Her hand caressed the bamboo flute slowly.
"Have some rest, you're going to go on a long journey."
"You should rest too, Senior Sister Chen."
Afterwards, Nan Hua bid her farewell and left.
