Hush! (2001)

Naoya and Katsuhiro are boyfriends, new in their relationship. Things are uneven at first—Naoya is open and free while Katsuhiro is cautious and closeted—but nothing compares to the chaos that arrives when Asako, a troubled woman with a history of psychiatric problems, abortions, and casual sex, asks Katsuhiro to conceive a child with her.
