I continued gameplay with Karkhel's posted save file and got every cg except for 5 and 6 as those were already missing (and I am not going back to get them because this game just ain't worth it). I don't think the order in which you chose jobs or apartments mattered. CG completion gameplay was entirely linear with "bad endings" consisting of a sprite scene or two with several lines of dialogue at best (no actual h-scenes). Don't waste your time playing this, I wish I could take my time back.
If anybody cared for dialogue/text for their CGs (the CG gallery has no dialogue), then you can load one of these saves to read most of them:
Save 1 = CG 8a* May NTR Creta
Save 2 = CG 8b* Creta Livestream Masturbation
Save 3 = CG 10 Creta finds May riding a man at the Club
Save 4 = CG 11 Creta, May's Slave
Save 9 = CG 12 Creta Threesome Rape
Save 10 = CG 13 Creta Beach Episode
Save 11 = CG 14 Creta Hypnotised at the Church
Save 12 = CG 15 Creta and Cow + Fisting (WARNING: Beastiality Content)
Save 13 = CG 16 Creta at the Shrine
Save 14 = CG 17 Creta and the Goddess
Save 15 = CG 18 May Threesome Rape
Save 16 = CG 20 Creta + May Together Good Ending
*For some reason, the CG gallery has two CG 8s (I am assuming the second one is meant to be CG 9), but I will just label them as 8a and 8b in the unlikely event there happened to actually be an actual CG 9.
*When renaming the save files into file5-file8 I was unable to see them in the load menu, thus I pushed every save to 9-16 in case this issue persists for others.
*Download the .zip and extract into the game's main directory.
