He wants to adopt a younger sister, but his aloof wife disagrees.

Left standing alone on his wedding anniversary, Jiang Che impulsively picks up a street-side runaway: a rebellious young woman sporting loafers and heavy smoky makeup. But beneath the facade lies Su Xiaoruan, an angel-faced chaotic spirit whose unfiltered internet slang proves endlessly entertaining. Amused, Jiang Che decides to take her in as a younger sister and launch a personal "makeover plan." Only, the plan takes an unexpected turn. Seeing her husband dote on their new houseguest, Shen Qingge—Jiang Che’s famously cold and aloof wife—begins questioning her own marital strategy. Abandoning her icy composure, the proud career woman shockingly decides to fight fire with fire by donning JK uniforms and learning the art of acting coquettishly. Panicked, Jiang Che tries to draw the line: "Wife, calm down, those clothes are for Xiao Ruan!" Pouting, Shen Qingge refuses to back down: "I don't care! I want to be your baby too!" Watch as an innocent desire to adopt a little sister inadvertently forces a frosty executive wife into a pampered, clingy queen of aegyo.
