I have the same feeling and the same privileged route.
At the end of ep.3, I agree, I think going with Derek is the right thing to do if you want to stay on this route.
Going with Sage may be interesting (in the future) if you are on DIK affinity path, and we know Josy & Maya are rather neutral / Chick.
Going with Bella will increase feelings for her and develop some kind of complicity... It may cause problems sooner or later. For now, being in relationship with Josy, Maya, Jill and Bella (so on the Chick side of the force
) is easy. But at some point, MC will have to choose (no harem said DPC). And the deeper relationships are, the harder will be to split !
I've done a lot of saves, particularly on the Josy&Maya route (my favourite too !). For instance, I payed attention not to be too close to Bella and Jill (no shower together and no kiss during Jill's date, avoid Bella when it's possible, etc...) to really increase my chances with Josy and Maya.... The future will tell us if I'm right !
If you want to try something without Josy and Maya, I think it's already possible, even on the Chick path, even if you refuse to smoke weed, etc... Just reject them on episode 4 (stay friends
) and, in episode 5, when Derek ask you if you're ok with the girls (in the preps house, when he checks the fridge), just answer 'Yeah" ! I don't know if the door will be definitely closed, but it's a first step...
