There Are Beautiful Men Everywhere in the Beast World, and You Have to Survive in the Shura Field to the Extreme

[1VN + Beast World + Heartthrob + Stamp-Collecting Male Protagonist] [Brothers turn against each other and become enemies, competing in the Shura field. Men are clean and women are impure. The female protagonist suddenly changed, she no longer beat or scolded them, and she became considerate of them everywhere... The beastmen, who were originally on the same broken boat and had to live in harmony, finally gradually came up with their own little ideas. At first, they could resist their desire to be exclusive. But the female protagonist who was once vicious and willful and committed all kinds of evil became a family-friendly female who led them to the waste planet, restored their reputation, and lived a good life... They began to indulge in the female master's gentle caresses again and again, and could no longer tolerate her being coveted and shared with others... Gradually, the former brothers began to turn against each other... But this is a world of beasts with many females, young males, and one-on-one is destined to be impossible... A group of beastmen who wanted to monopolize the female master attacked fiercely, but they made things difficult for Jiang Suisui, who came through the book and took the beautiful man's stamp collection system, and no one dared to "offend" her. (The plot of Shura Field will start later, and the heroine will get rid of her "evil female" identity relatively quickly.)
