It is advisable to make multiple saves on Lover path as well as the other paths. Each save consists of different choices you made compared to the others. Take mine as an example. In Lover, I have about 4 total saves. 1 save for lewd path, another for conservative path. I also have 1 for good choices, and another for bad choices. So by endgame, I assume I will see different endings for each of the 4 saves. Not mentioning that all 4 saves allowed me to unlock pics depending on the choices I selected. This is how I managed to unlock all 661 total pictures as of v0.21
