After making choices, check your status through your phone, that should give an idea. Minor choices don't matter that much, but the big ones that take a portion of the Affinity scale do matter. You'll see the DIK bar when those choices at the top of the screen, for example asking Steve what happened and talking to him loses you 1 portion of DIK Affinity. I would recommend you to go hard on CHICK and DIK on 2 saves, then going neutral, but most important one is choosing whatever you feel like for the first time. Cheers
