I remember that the reason the Protagonist was ment to be androgynous at the start of the game is because the game was going to have 3 paths one were he became more masculine, one where he became a trap/trans/sissy and another one were he became a woman.
Due to complains from people who didn't liked trans content like those comments you can see under this post from 2023 they reworked/rebooted the game into just the Masculine and Female paths, but now i think they have also dropped the plans to add the option to transform The Protagonist into a woman since we can no longer see his female version artwork anywhere else apart from the banner of this post where you can see a androgynous guy on the left and a female on the right with the World of Secrets in the middle. The Female on the right was going to be the female/feminized version of the Protagonist
So it seem from itch.io page and the title that they gave to "season 1 grow into manhood" that they only plan to develop the masculine path, he is going to go from androgynous to more masculine.
Edit: yeah they confirmed to me in their discord that the idea of the Protagonist having a path where he feminized and becomes a female has been discarded instead they would only develop the path where he would become more manly/masculine has the story progresses and they would introduce in a update a female protagonist has part of the story, they said it would be spoiler to reveal more.
