you have caught an important point in the matter.
an important problem, especially evident in the sixth chapter, is that despite being a real route, there are no contents for friendship with Maya and Josy, they are exactly the same as the route of the trouple with exclusions (of course all the sexual scenes, but also others in a fairly arbitrary way). I really believe that the only "dedicated" addition is the greeting message instead of the phone call ...
and this is quite absurd.
if MC is related to them it is absolutely right for Josy to call him, a little less necessary is for MC to ask Maya again to be honest, if they are together she should take it for granted. but in case they were just friends at least the dialogues shouldn't have been different? for example Josy could have insisted that MC go to them that evening, more gratitude ..
in real life a friend who always calls you when he needs and is not present in the same way when you are in need (in the sixth chapter for example when Mc has to fix his room, but in general MC helps or can help Maya in the scavenger hunt, the opposite is not even contemplated, not even for the slap) is not a great friend. what do Maya and Josy do to be friends with MC? there was and there is a need for specific content for this route otherwise it really becomes a punitive path (even more so considering that not all the players who are on that route are so by their will)
