She Refuses to Compete with the Female Partner

In the Midst of the Book Shortage... I Hope the Heroine of Hei Yuan Is Not a Female Protagonist.

Why do so many fast-travel redemption novels with gloomy male protagonists have a Kurohara heroine? It feels like there are more than just quick-travel novels, so does it have to be a Kurohara heroine? Can't we develop independently? I feel like the Kurohara heroine is more or less unbearable now😱
