I have still yet to see the repercussions of a lot of actions in the game, and I am fearful they will be added later. That is why I have been doing multiple runs. I strongly dislike the wife and shoot her down at every turn all the while romancing the purpled haired girl I hope I can end with. Others say that the wife can become into your actions with everyone in a harem ending, but I don't want her at all, I want purple to win protag bowl. Problem is the idea of being faithful in this isn't really possible. The game and the girls push other girls onto you, and while they seem chill with it, something has to give at some point. So basically I have 1 run being totally loyal to the purple haired girl to the best of my abilities. And another that is the same, forget my wife, romance her, but actively fuck everything that moves but doesn't romance them. Also, with the scene with purple asking something to the extent of "only one for me and a lie would be trouble down the road" I am not sure what that entails. She's the only one I ever pressed romance text with... but I did fuck everything that moved in one save or everyone she gave me in another.
I just want a right answer to marry my purple waifu
