Lin Xiaoman, a fresh graduate, accidentally saves Su Wanning, an ice-cold CEO being chased, and binds to the "Sister Protector System" — he must get Su Wanning to agree to his proposal within 30 days, otherwise he’ll trigger the "social death buff" (dancing children’s dances in public or spouting cheesy pickup lines). But Su Wanning only sees him as a "little brother who delivers the wrong files"—until Lin uses the system’s clues to retrieve her childhood teddy bear lost for 15 years, uses a "business tip" to resolve the company’s merger crisis, and even shields her with self-defense skills when she’s kidnapped… When Su finally realizes the "little brother" has long been in her heart, Lin stands downstairs with roses: "Sis, this time it’s not a system task—I’ve wanted to marry you for a long time."
