Hello, ACanOfDrink!
My apologies for the delay in responding.
The loss of control is gradual and depends on multiple factors, such as corruption, fidelity, reputation, and the protagonist's choices, among other things.
As long as fidelity is kept high enough and overly risky decisions are not made, one would be on the safe route.
Regarding the Harem, if you want to form it, for now, go for all those that lead to a better relationship with Adara and the wife. In the future, there will be many more options, and each will have its ways.
I hope I have answered your questions. If you need anything else, I'll be delighted to assist you. If you wish to share your ideas or get more information about the game, you are more than welcome in our Discord Community.
Thank you very much and have a great day! 😊
