Sound of Fireflies

Lost dreams and puzzles of time and space will always leave a gap between yourself and the world. In 1997, Xia Zhiyan from Xiaoyang Town in the south "accidentally" fell into the lake in Yinghuo Park. In 2018, Tang Anran, who was living by a small lake in the countryside of Tongcheng, encountered a group of fireflies that suddenly rose... After waking up, she lay wet beside Yinghu Lake, becoming Xia Zhiyan in 1997. While looking for a way to return to the future, he experienced various grudges and resentments in school as Xia Zhiyan.
