Modern girl Lu Youyou transmigrates into a love-brained supporting character in a CEO romance novel, also becoming a rabbit spirit whose ears pop out whenever she gets emotional and who periodically reverts to her original form. To secure a divorce settlement and run away, she desperately acts out, but cold-faced CEO Qin Du overhears her true inner thoughts. Qin Du, originally set on divorcing, sees through her act and plays along to keep her by his side. From mutual probing to cohabiting and protecting each other, slapping villains in the face, and healing traumas, Lu Youyou gradually becomes Qin Du's soft spot that he can least bear to let go of. Season finale: she is forced to revert to a little rabbit in distress in a back alley, and Qin Du recognizes her at a glance and saves her, her rabbit spirit identity about to be unveiled.
