Yonosuke is a wealthy member of the bourgeoisie and a fervent follower of the philosophy of good living and good love, two aspects to which he has devoted himself body and soul with enthusiastic devotion. Throughout this novel as exceptional as it is funny, we will discover the most significant episodes of the life of this incombustible heartthrob: from his debut in the love arts spurred on by an unusual sexual precocity, until his departure, about to turn sixty, heading to the mythical island of Nyogo, a land of legend inhabited only by beautiful women. Six decades in which Yonosuke savours the delights and sorrows of love, deploys his weapons of seduction and develops a formidable erotic talent that he will generously share with the 3742 women and 725 men who will enjoy his charms.
