A girl suffocates under her broken family so completely that she'd rather be a cat than herself. That's the real story here, not the romance. The movie knows that loving someone and hating where you come from can feel like the same desperate thing, and it doesn't flinch from how ugly that desperation looks before it breaks open into something real.
Miyo Sasaki is suffocating under the weight of her fractured home life. Her father checks out emotionally while her stepmother's relentless attempts to bond feel suffocating rather than warm. The only bright spot is Kento Hinode, a classmate who represents everything stable and good that her family isn't. Problem is, Kento barely knows she exists. Then Miyo discovers she can transform into a white cat, and suddenly she has Kento's full attention. As "Tarou," she's playful, beloved, able to be near him without the crushing anxiety of being herself. For the first time, someone actually wants her company. But comfort becomes a trap. Overhearing Kento's real struggles from the safety of her cat form, Miyo realizes she can't actually help him this way. She's caught between two impossible versions of herself: the cherished pet or the vulnerable girl who might get rejected. Staying hidden feels safer, but it also means never truly being known by the person who matters most.
