Yep as a guy mainly playing through Chloe's route(along with several hookups of course) I felt exactly that specially with the bug that she is not even recognised as the winner of the Fraternity elections, even if she is a poster girl she has not been dedicated the right moments and scenes for us fans to actually care about Chloe beyond the superficial level.Couldn't agree more
Her past relationship drama with Grayson is also left unresolved only for you the player to connect the dots and let me say that there aren't many.
Remembered right now the take care of a robot baby event, you barely spend time with her then and there are absolutely no sex scenes in between, is like you have all that compatibility but your MC is treated more like an errand boy than a boyfriend, ever calm to Chloe's constant displeasures.
That plus we don't yet much of her background and family like compare that to Aubrey(or Lauren's case when we meet her sister) where we actually met her parents and sister, is like I say not poster girl treatment.
