Ji Miaomiao gets a second chance at the worst possible moment, transformed into the one thing that can't talk back to the man she's terrified of. Every interaction is a collision between what she desperately needs to say and what a cat can only express through looks, proximity, and impossible timing. She has 100 days to figure out if Lu Chengze's kindness to a stray is actually kindness to her, or if she'll spend them suffocating in a body that can't bridge the gap between them. The show's real cruelty isn't the debt collectors or the fall, it's watching someone rebuild trust from complete powerlessness, where every purr and headbutt has to carry the weight of confessions she can't make.

Ji Miaomiao is just starting out in her career when a friend betrays her and leaves her buried in debt. Running from merciless debt collectors, she slips and falls from a building. As she hovers near death, a mysterious figure turns her into a cat. By a strange stroke of luck, the person who adopts her is her own boss, Lu Chengze, and so begins her odd, magical hundred days of life as a cat in this supernatural romance ONA.
