No, I'm not messing with Cathy, not chatting on the app, just driving her home, dating Jill, and having relationships with all the main characters. Is there an effect on Jill and Bella's ending in EP.7? I always try to maintain the CHICK value.You can only shower with Jill if you have CHICK affinity, not Neutral or DIK. You can't get the ep 7 scene if you are DIK affinity or you helped Sage when she was sick instead of going on date with Jill.
As for the Bella issue, did you get the oral sex from Cathy?
