Why do Otoyu girls like Ky so much?

Satisfy your inner love needs. The purpose of the Otoyo Girl game itself is to allow players to take on the role of the heroine and interact with male characters to satisfy their inner love needs. In order to achieve this goal, games generally give players the right to name themselves, and also give the female protagonist the option to branch out into the plot. While giving players a certain degree of freedom, they also recognize the rights that players have in the game.
