Wen Ruan, a princess who escaped from marriage, sneaked into the Chengnan Academy incognito and wanted to live a low-key life, but she bumped into Lu Jingyan, a substitute teacher who was rumored to be strict and cold.

However, as the interaction between the two deepened, Wen Ruan suddenly discovered that this arrogant young wife who was so controlled by him was actually the fiancé that he desperately escaped? !
