Not every game has to have the option to choose your gender. Is it really so difficult to understand? The devs wanted to make the game revolving around a female student. It's up to you if you want to play as a female or not. If you don't then just don't play it. Sorry if I came off as rude but it was getting kind of annoying to see so many people saying the same thing when the devs clearly mentioned it in the game description.
