A boy and a girl who were opera classmates in primary school. When they were sixteen years old, due to a misunderstanding, one of them stayed and became a decent Kunqu Opera teacher. The other lived in seclusion in the ancient town of Yaoli, singing Kunqu Opera alone in the ancient stage. Ten years later, when they meet again, can they put aside their bad feelings and continue the song "The Peony Pavilion" together?
