Hetun (2011)

Xiao-Zhun's world is like the elevator she operates in a department store: static, polite, low-key. When she catches her boyfriend cheating on her, the shy girl decides to find a better home for her pet blowfish. A lonely baseball coach purchases the blowfish at an internet auction. He is waiting in his trashed home for his wife, who left him. When Xiao-Zhun takes the Blowfish across town to his house, they make passionate love in the surreal blue light of his aquarium. She stays with him, but their love staggers like a blowfish… until one day, the Coach finally wants to learn this girl’s real name.
