Maybe it's just me but I think he's making this up as he goes along, I hope I'm wrong though. Early on with the "don't add" path, I thought the MC was actually going to try to be the good guy and try to solve the mystery and save the girls. I was thinking it was going to lead to an interesting game where you watch the girls get corrupted and try to save them.
No, it isn't just you, it's actually caused by the dev since the game's content is mostly developed based the votes at his Patreon page.
Up to the point where the MC is looking for a new job is the foundation of the game and holds the 2 main choices for what route the player takes (Add / noAdd, and NTR off / on), the noAdd NTR off route (Alpha route) gives you at least the most impression of the MC actually trying to get back at the people that screwed him over.
The AddWife Alpha route barely holds any story progress, sure, you can the wife save from getting corrupted, but so far the only "progress" there are the Sola, Mrs Salim and Paul(a) branches without providing much results in solving anything.
The majority of the branches are also not connected, a choice made in one branch doesn't effect an other.
It's basically a collection of independent stories that sometimes refer to each others events, or only happen/progress after a certain step has been passed.
TL;TR: The noAddWife Alpha route branch is imo the only thing that could be considered a main story that might see an actual end by solving the MC's issues.
edit: to make the AddWife NTR off route actually work it needs it's own Alpha Story branch with some progress conditions down the road that are asking for milestones in other branches to tie them together. Branch steps like Sola's father starts to trust the MC more and more, Paul(a) finding important intel, getting more influence over Mrs Salim, and what not. (maybe add the Mike Feminization story from the noAdd Alpha branch as it's own branch to the AddWife Alpha route to get back at Jenna there too)
Give the Salim Debt branch more meaning by adding the condition to each Alpha branch step that it only can progress when the Debt branch stays at step 1.
At least for the AddWife Alpha route, doesn't matter for the noAdd Alpha route since the MC has more or less given up on his wife and would most likely not care about her meeting Salim, i mean he doesn't get fazed much by his brother openly confessing he is about to get his wife drunk to fuck her, since he got sick of corrupting her into willingly wanting to have sex with him.
edit2: as a suggestion, an additional Wife+Salim branch should be added for the noAddWife Cuck and Sissy routes where the devs and/or Jenna telling or teasing the MC about was is going on at Salim's club. Without access to the wife's phone the MC's Salim Debt branch does basically nothing on it's own besides Salim talking about what he wants to do but not showing any consequences.
