Sometimes we feel the need to transform ourselves for someone else. However, this doesn't always produce the results we expect. "Siu siu" a Cantonese expression meaning "a little" but literally translating as "small small", focuses on a lonely, isolated man who routinely attempts to catch the attention of a woman he secretly loves. It takes an exchange of heads with a hairy caterpillar for a chance to get closer to her. At first this exchange appears to have produced fantastic results, but nature begins to take control and the character finds himself on a new path.
