The medical girl Su Murong lives in seclusion in Qingya Valley, collecting medicines and practicing medicine without caring about worldly matters. Once he rescued the troubled prince Xiao Heng, they stayed together day and night, and a secret love arose. When he recovered from his injury and returned to the capital, she only stayed at the bamboo window, looking forward to his return. He promised her thousands of miles of mountains and rivers, but she only wanted him to put aside his glitz and sleep together in a dream of mountains and rivers.
