What I can never understand tho is why leaving him is not in his choices. I mean sure everything went nuts but does the mc really love him enough to stay or is he to proud to quit his job because he doesn't want to give in to the injustice? Like it's not making sense for me rn help

P. S. I'm not downplaying his situation where he is being manipulated and isolated. I just don't know which one is it that's keeping him there now that the friend is gone
