Air Doll (Kûki ningyô)

An “air doll” (played by Du-na Bae) suddenly develops human feelings one day. Without her owner knowing, the air doll decides to walk around town. She then falls in love with Junichi, whom she spots while walking the aisles of a video rental store. She then starts to date Junichi and eventually works at the video shop. Everything seems to be going perfect for the air doll until something unexpected happens to her.
