IDK if you are still looking for it but with the console (Shift + O) insert this code:
persistent.watched_h_scenes = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54]
To make sure that you can open the console install the UnRen file from F95 Zone
Extract the file in the same folder as the game and execute it, after that press number 7 and the console should be available
