Yun Shu had a secret crush on Xiao Yan for seven years, but was used as an abandoned child by the Lin family to marry Zhou Xing'an in an arranged marriage. On their wedding night, Zhou Xing'an left an agreement to not interfere with each other before going abroad. A year later he returned, and the two went from strangers to familiar, from mutual respect to growing ambiguity. Zhou Xing'an flipped open Yun Shu's secret crush diary, jealousy surging yet refusing to admit it while being domineeringly possessive and gently indulgent on the other side. Yun Shu finally fell for him, but proposed divorce due to the Lin family's entanglement and reproductive pressure. Zhou Xing'an refused to let go, and after a crematorium-level wife-chasing arc, the two cleared up their misunderstandings, held hands to head abroad for studies, and spent every morning and evening together.
