Nothing has ever gone right for Riki. She left her boring hometown in Hokkaido, where she worked at a nursing home, for a better life in Tokyo. But as a temp in the big city she has no job security, and barely scrapes by. She eats the same old discount boiled egg for lunch every day, sometimes for dinner, too. Many of her peers have to take on a side hustle just to make ends meet. So when her friend discovers an agency offering a hefty sum for egg donation, both leap at the chance for an interview.

Meanwhile, former ballet star Motoi Kusaoke and his wife, Yuko, have been trying to conceive for years. After trying what feels like every available option, it seems futile—until Motoi dives deep into his research and learns that, while surrogacy is technically illegal in Japan, there is a company that’s found a loophole.

Before long, everyone has an opinion on the matter: from Yuko’s sex-obsessed, asexual best friend, to Motoi’s controlling prima ballerina mother, and even the affable sex-worker-slash-therapist that Riki has been to a couple of times, after she accepted a down payment to be a surrogate.
