Well, no matter what you do, you're still forced to be best friend with Derek too. For the sake of the plot, we can't really ignore any LI. For better and for worse, even if we choose to reject them, they're still central part of the story. They're also connected to others major characters (Derek, Tommy, the Hots as a whole...). Take Josy for example, she started a friendship with Jill, there no way she'll just disapear just for the MC. At least, the player isn't really force to "help Josy" in ep5. Who knows ? Maybe M & J could grow to dislike the manwhore Dik MC
