Xia Fan is a regular visitor to the Life Records Hall. She plunged into the vast collection to find the life record of "Jiujiu," the instructor who had kept her company when she was little. It was like searching for a needle in the sea, but she never gave up. The "partner" who joined her search turned out to be an angel who appeared out of nowhere. The angel seems to have forgotten something, and Xia Fan's memories of her are hazy, too. As Xia Fan searches for Jiujiu's life record, major events begin to come to light, and clues emerge one after another. Meanwhile, Xia Fan's memories of the angel slowly return, and her feelings for her gradually blossom... The angel descended to earth for Xia Fan alone.
