Heyy, I'm super glad you like the game!
There are other girls you bang in the story, and I haven't made it optional.
It isn't made in " secret " to Emelie though, as it is addressed in the writing between you and Emelie.
I might consider making a route that's 100% all about Emelie once the game is completed, but it would require rewrites here and there, and a TON of content would be cut for that route, so I don't want to do it now when chapters would be cut sooo short if people just skipped the side-girl character content.
Thank you for the kind words!
