Twenty-something Michinosuke Onmyōji is the son of a famous politician. As a child, he was a girlish boy who loved to draw, and as he came of age he realized that he had a romantic preference for boys. In art college he was secretly in love with a guy in his class named Takase, but never found a way to let him know before graduating and moving to Paris to continue his studies. One day Miharu Habu, a charismatic Japanese author of hardboiled fiction, comes into the café where Michinosuke works. She says she is currently at the fine art printing studio Idem Paris, whose lithographic equipment many famous artists have used, including Picasso. Through on odd sequence of events Michinosuke ends up visiting the studio and is so blown away by the prints he sees there that he begins creating some of his own. Meanwhile, Habu is experiencing writer’s block, and is unable to make progress on the promised next title in an international bestseller series she publishes. She’s been successfully evading a publisher’s agent sent from Japan for some time, but he finally tracks her down at Idem.
Around the same time, Takase comes to Paris on business and Michinosuke meets up with him, but their reunion is interrupted when they get enmeshed in Habu’s sudden flight to Deauville. Then Takase breaks Michinosuke’s heart by mentioning the woman he’s in love with; Michinosuke keeps his own feelings for Takase to himself and offers encouraging words.
When she hears Michinosuke’s tale of woe, Habu says that if she’s ever able to recover from her writer’s block, she’s going to write a story based on him—except with a happy ending instead. Those are heartwarming words for Michinosuke, who has endured the loneliness of being different all his life. He determines to join the lithograph studio and make a new start as an artist. And he also finds love again—with Habu, who has finally recovered her writer’s magic. She has started on a new novel called Romancier (Novelist). About an aspiring artist very much like Michinosuke and a writer very much like Habu, it is to be the sort of romantic comedy where the reader will burst out laughing every five lines or so—and from time to time shed a tender tear or two as well.
