I've seen this a lot.
Is there a particular reason people play that way? Is it just that they like games where they play a female protagonist who cheats on her husband, and so it's just that aspect of it here? Or is there something else that I'm missing?
Personally, my MC fucks everyone including the husband, as I want to see all the content she has. The only exception was Dale early on, as I don't like him enough and didn't want to be involved in him cheating on Vera! (And I made an exception for the teacher - I originally turned his scenes down because I didn't want the blackmail here, but once he suggested bringing Chloe in, I couldn't resist!)
