I don't spoil anything so I'll just say that you'll have to wait and find out yourself :)

damn,was hoping for a tiny hint,but......i can wait,a couple of things i noticed when i first played through without the guide,Cathy's subtle bit of jealousy when first meeting Riley and everytime after that when Riley tried to put herself between Cathy & MC,particularly at the club in toilet stall with Chloe saying she wants to punch her in the face,i also read one of the comments from 20 days ago when someone brought up harem for some of the Li's in the story,which is why i prefer Cathy & Chloe for that,at least for the 2nd playthrough i'm currently doing with Cathy & Chloe,then do a playthrough with every other one afterwards,halfway through Riley's route and when the choice to comfort Cathy after visiting her father but to leave,that hurt to do that choice
