Hajime - "Beginning" in Japanese - was an atypical only child growing up in a conventional middle-class suburb. Shimamoto, herself an only child, was cool and self-possessed, precocious in the extreme. After school these childhood sweethearts would listen to records, hold hands, and talk about their future. Then, despite themselves, in the way peculiar to adolescents, they grew apart, seemingly for good.
Now, facing middle age, finally content after years of aimlessness, Hajime is a successful nightclub owner, a husband and father, when he suddenly is reunited with Shimamoto, propelled into the mysteries of her life, and confronted by dark secrets she is loath to reveal. And so, reckless with enchantment and lust, Hajime prepares to risk everything in order to consummate his first love, and to experience a life he's dreamed of but never had a chance to realize.
