The orange cat "Tangerine" who lives in the attic of a grocery store in the old city is always curious about the pigeons flying outside the window, the strange smells wafting from the alleys, and the flowing clouds on top of tall buildings in the distance. In the morning after a heavy rain, it finally mustered up the courage to jump out of the familiar window sill and embark on an adventure in the city - from alleys full of old things to rooftop gardens full of sunflowers, from bakeries deserted late at night to underground garages hiding secret bases for stray animals. Tangyou used his paws to measure unfamiliar lands, discovered the neglected warmth in the human world with his eyes, and learned trust and bravery from accidents. When the city's neon lights lit up again, it finally understood: adventure is not about escaping, but about returning to the people you love most with new stories.
