I ment a walkthrough for the conversations/choices
Choice 1: At the start of the game you will be asked to become an incubus. Yes makes you a chad. you fuck all the girls. No makes you a cuck, another man is the incubus and he will fuck all the girls in your life, stealing them away
Choice 2: Your maid's daughter has 2 routes, romance or discipline. Choose the one you prefer.
Choice 3 & 4: two girls give you a choice on how they will look after you transform them into demons
Choice 5: one of the demon girls will give you a choice on her new default boob size after her curse is lifted. (she can still temporarily shapeshift those though)
Those are the only choices in the game.
Every time you talk to a girl you gain +1 affection. Typically every 5 affection points you will find that affection can no longer progress until you visit a certain location (varies) and trigger a cutscene which will advance her transformation and unlock raising affection again.
You do not make any choices when talking to girls. It is an automatic scene whose content depend on the girl corruption rank as well as on whether you are a cuck or a chad.
Well ok, if the girl is highly corrupted then sometime when you talk to them you will get a choice like "fuck girl A" or "fuck girl B". it has no effect on the game and you can repeat it as many times as you want
edit: note that this lack of choice is not necessarily a bad thing. I am enjoying this game a lot. Just saying that a walk-through is redundant
