Pet blogger Su Xiaoman encountered a large-scale "social death scene" during a live broadcast - when she was bragging about the aristocratic lineage of her Ragdoll cat "CEO", the cat suddenly vomited hairballs in public, and was spotted by Lu Yuanchuan, a vicious-tongued veterinarian who was passing by, who saw that the cat was improperly fed. The two formed a close bond, but as fate would have it, when Su Xiaoman's stray cat rescue center faced a crisis of demolition, the only one who could provide help was Lu Yuanchuan's animal hospital. One is a showman who trades "Old Iron 666" for cat food, and the other is a perfectionist veterinarian who treats the operating room as a church. In this "battle to defend cats," who tames whose heart first?
