I think that Emma is a mess. Definitely, she required an almost exclusive new game (or new game+) for her alone.
There should be an achievement after finished her story, like
"Congratulations you frienzoned, dumped, avoided all the girls in game-including your adopted sister-, just to following the girl of your (wet) dreams!. Here, player, you, the real one, the guy/girl behind the screen, take these five thousands dollars (in game only) as a reward for your dedication, patience and self-control. Now go, you are free to screw anyone you like (in game only)".
