Well, after playing this game, I searched for games with the same logic, but none of them gave me the pleasure I got when I played Personal Assistant for the first time.
A couple I would consider close below:
1. Slightly more direct with less grind. Live in corruption This is a remake of cohabitation which is complete at this point. I like the remake more.
2. Older game but does the corruption route 2 ways. Slower with the daughter like PA, more direct with the mom. Lucky Mark it also has a renpy port, but I prefer the official version.
3. The regional manager. Direct abuse of power game. It is abandoned at this point dev had some family issues. It has a lot of content though. Might need to google for DL.
4. Hack N stalk games 2/3 I think more so than others. Overall most games from this dev have slower corruption elements.
