I'm so dumb I just wanted to see a little bit of spoilers of the CG's and messed everything up with Haruki by mistake T-T
Anyway thank you so much for help me! I tried to uninstall the game from Steam but all the data remains there.
Try replacing this save file to get the initial Haruki Madness end (same location as where the patch is applied)
