Tabata plays Anzu, a housewife being pressured to have a child by her mother-in-law and being forced to undergo fertility treatment. Through her hobby of anime and cosplay, she meets Takumi (Nagayama), and their encounter turns into a love affair. The story follows their complicated and painful relationship, including Anzu dealing with pregnancy and childbirth.

Based on the award-winning novel of the same name, this boldly erotic yet movingly tender portrait of a group of vulnerable, variously wounded people — a depressed housewife, her high-school-aged lover, and his best friend, who is struggling to provide for himself and his senile grandmother — whose intersecting lives yield both sorrow and a fragile, yet enduring, hope for a brighter future.
