Su Mian, a kind-hearted illustrator, agrees to foster a kitten for her best friend. What she thinks will be a simple favor soon turns into a nightmare when her friend disappears, shirks responsibility, and demands an exorbitant amount of compensation. As the kitten's condition becomes critical, an eight-year friendship falls apart completely, and Su Mian finds herself at the center of a public backlash. Lu Yanzhou, her cold and aloof landlord, initially insists that the cat can stay for only three days. Yet when things become desperate, he never leaves her side. As surveillance footage, money transfers, and an abandonment document gradually come to light, who is pretending to be innocent, and who is lying? This time, Su Mian decides to stop pleasing everyone and use evidence to fight for justice, securing a place to call home and a better tomorrow for herself and the kitten.
