Hi asphyxia! Of course for story reasons I‘d have to say no, but if you really want to replay it, you can download the game or delete the persistent files if you played on a downloaded version already - those are the ones that control the story progression!
RenPy games have two separate persistent files. The first file is simply found in the folder you dowloaded under „game\saves“ and is called „persistent“.
The other one is under „C:\Users\user\AppData\Roaming\RenPy“ Just select the RenPy folder, find the „DatingSim389“ folder inside of it, and delete the persistent file that one has as well.
That should take care of everything :)
