So is Cindy cheating with Axel and cucking Ian and Wade unavoidable?
Love route in general. If you set boundaries she will stop it all together. If you trust her, Axel will touch her a bit, but she will stop it, because of you, so that is not cucking and isn't really cheating, maybe the start, but ai don't count it as cheating.
The set boundaries path is the best path right now, but both paths of setting boundaries and trust will stop it, it will just play out differently.
