Rat's entire arc is falling in love with a cat and then deciding that cat's only path to happiness is joining the celestial bureaucracy of the Zodiac. The show takes this absurd premise completely seriously, which means watching twelve mythological animals conduct very formal interviews with one extremely confused house cat. It's the comedy of watching someone's sincere desperation collide with cosmic indifference, played straight until it becomes something genuinely warm.
A stray cat crosses paths with Rat at a neighborhood park, and what starts as a casual encounter blooms into something neither expected. Rat becomes utterly smitten, convinced this ordinary cat deserves a place among the twelve zodiac animals. The problem: the zodiac roster is already full, and the other members aren't exactly waiting around to audition newcomers. Determined to make it happen, Rat drags Cat on a series of visits to meet each zodiac member. These encounters range from awkward to chaotic as Cat tries to prove worthiness to a cast of mythical personalities who have held their positions for centuries. Some members find the whole thing endearing. Others find it ridiculous. A few are actively hostile to the idea. What unfolds is a comedy of persistence versus protocol, as Cat navigates an absurd celestial bureaucracy and the colorful egos guarding it. It's silly, irreverent, and driven entirely by one rodent's unshakeable belief that love can restructure cosmic order.
