To a Gentle World Where Chastity Is Reversed

A man in his late twenties, with no clear reason to live, no friends or lover, and who has lost all confidence in himself. One day, he wishes for a world that would be kind to him—free from malice—and then, he realizes the world has become just as he wished .
A world where the male population has drastically declined. A world where women's sexual desire has increased. A world where sexual relationships between men and women have become rare. A world where all women long for advances from men. A world where most men even feel fear toward women.
In this world he wished for, the man meets several women who genuinely like him. As he builds relationships with them, little by little, he begins to regain his self-confidence. This is that kind of story.
