Chapters I and II do not have a very present NTR / sharing content. In chapter III the existence of this type of content is more explicit, I believe that the MC has become more "passive" in this chapter because of the inclusion of these contents.
NTR / sharing fans will defend the idea that the content is optional, but it does not change the fact that the inclusion of these contents affects writing in general.
For example, they added a pervy grandpa and a nerdy cousin with a big cock in chapter III to participate in these events in the future. Even if you disable the optional content they will still live at the MC's house. It will be the first time that I will see a harem game with men (pretty strange to be honest).
But I believe that with all the inconsistency, Max's Life is still a great game.
