灰烬 (Huījìn)

Background
"Huījìn" is an original duet song featuring Luo Tianyi and YANHE. It was originally uploaded on October 4, 2013 and later received a remake in 2015. The remake became more popular than the original version. It is followed by "Zhuó zhī Huā".

According to COP's Lofter, YANHE is a while Tianyi is a person who accidentally entered a yard at dusk. "Huījìn"'s abstract is described as followed: YANHE, being a flower spirit, appeared after the dusk, and accidentally meets Tianyi who entered the yard. They fell for each other as time passes. However, a flower spirit will turn into ashes after any contact with humans. YANHE doesn't tell the truth to Tianyi. At Tianyi's will, they made love. Tianyi discovered the unusualness of YANHE, but could do nothing to help. Under the moonlight, YANHE asked Tianyi to turn around and held her in her arms as she turned into ashes bit by bit while Tianyi witnessed the withering away of roseleaf brambles, feeling the decreasing weight hold her until it finally disappeared. Only coldness remained at the daybreak.

In the, a roseleaf bramble means "the beauty of the dead end". It means the end of an emotion and the fading away of the most unforgettable love, leaving decline after the prosperity.
