Probably? I know my own personal goal is to make it so that nearly every visible character gets at least one sex scene, beyond that, who is dateable is really up in the air. The game's plot has an outline, but it centers more around the mysteries I've set up and not the relationships specifically and how they play out.
If you are wondering how to get scenes with specific characters, feel free to check out the player-made walkthrough guide in the #public-game-guides channel on Discord or the Official Walkthrough checklists available to patrons here
