It might be worth chasing more than one main girl option at once up to the Crossroads choice - it's not paid off yet, but the game keeps teasing certain threesomes might happen down the line.
This one will be my main save for future updates, in this case I'm in the interlude and I'll try to just go after Quinn, I don't trust DPC, I know that when the consequences hit for thinking too much with my lower head they will come strong.
Maybe I'll try to continue with Sage and see what happens with the others when I play again, but for now I'm not going to explore those sides yet, and I'll be honest, after what happened I feel relieved that I didn't pursue Jade after ep8 ending, I'm still in the interlude but I feel like it was a good choice.
