It defo won't be a harem.
For now you can be in a relationship with 2 girls,Lauren and Chloe, and both of them are not the types to share and both had displayed jealousy.If we get Nora after everything she went through with chris there is not a single chance she would be into it,
Penelope is even more reserved than Lauren so no chance there either. Emily(probably after charli will get discredited by mc and riley she will come back to trying to get back with mc) won't share for sure as she wanted to get mc back for herself (before charli that is),Riley is a big mystery,she was the girl next door type but now she seems to be more like Amber or Aubrey,and I don't know what they want to do with her character,she wouldn't mind mc fucking around now,but I think she'd rather have a monogamous relationship. Now we get to the wildest two,where Amber seems to remain on her free spirit path,while Aubrey is well on her way to accept mc as her boyfriend and I think If she agrees to do so,she would want to be exclusive. I think that only threesomes could happen,and only 3 girls would agree-Riley,Aubrey and Amber, I mean you can fuck everyone up until you h=get a gf,If you get one she will probably find out you are cheating on her and break up
