After ending a relationship, wedding planner Sang Nuan coincidentally chooses to flash-marry Pei Yin, the heir of the Pei family. Living together after marriage, she unexpectedly acquires the ability to read minds, allowing her to hear Pei Yin's inner thoughts. Pei Yin appears cold, reticent, and restrained on the outside, always putting on a distant demeanor, yet deep down he constantly praises Sang Nuan, worries about her all the time, and secretly gets jealous. Through daily friction and visiting parents, amidst a back-and-forth of probing and hesitant interactions, the two slowly drop their guard, shed their polite disguises, and gradually develop genuine feelings for one another, letting true affection blossom out of their flash-marriage in the details of everyday life.
