The secret of the aloof scholar Jiang Mofan is to feed stray cats in an abandoned greenhouse. When an ordinary girl, Meiru, accidentally breaks up, a cold "Don't tell" connects their fates. The cat's meowing in the middle of the night connects the secret guard, and his blunt message hides the hot heartbeat: "The cat misses you, and so do I." When malice strikes, he protects her behind him like ice. Until on a rainy night, when she was soaked and broke into a dangerous house to save a cat, he pinned her to the wall. The hot confession and the old bell around her neck together revealed the secret of life and death buried deep in his heart - that her, and the brave her in front of her, had long been tightly entwined with the same cat bell.
