Yaichi is a work-at-home suburban dad in contemporary Tokyo; formerly married to Natsuki, father to their young daughter, Kana. Their lives suddenly change with the arrival at their doorstep of a hulking, affable Canadian named Mike Flanagan, who declares himself the widower of Yaichi's estranged gay twin, Ryoji. Mike is on a quest to explore Ryoji's past, and the family reluctantly but dutifully takes him in. What follows is an unprecedented andheartbreaking look at the state of a largely still-closeted Japanese gay culture: how it's been affected by the West, and how the next generation can change the preconceptions about it and prejudices against it.
