On a stormy night, Sebastian Hawthorne, the powerful head of a fashion empire, rescues Elliot Wells—a young man with white cat ears—after he falls from a high-rise while reaching for a smoked fish, and brings him to his penthouse. Elliot desperately hides his ears, tail, and feline instincts, but keeps exposing himself through fevers, baths, shedding, and loss of control. Sebastian shifts from possessiveness to clumsy, concrete care. Elliot's suppressed design talent reawakens, and he becomes a dazzling new star at Hawthorne Fashion House. But Sebastian had secretly watched over him for three years and kept his belongings as numbered treasures—blurring the line between protection and imprisonment, shattering trust. Misunderstanding a cold corporate remark as proof that he is replaceable, Elliot flees into the rain and heads for the airport. At the final boarding call, Sebastian publicly confesses his control, his fear, and his love, and returns the choice to Elliot. Elliot stays, but demands to design the finale and present himself on his own terms. On the runway, he appears in black-feathered couture with his white ears and tail on full display, turning what he once hid into art. Sebastian finally admits that love is not possession. Back in the penthouse, the windows are left unlocked forever—and the cage becomes home.
