i wouldnt say Mia story is short(its kinda long considering you have to wait stages that take like 1 entire week without any advance to progress to the next stage),i would rather say it has little content involving Mia like the objective,since most of the story is about trying to make Helen stop to meddle with your relationship with Mia....you were there,trying to prove yourself to be THE GUY to her parents,witnessed the problems they had thanks Helen fanatism,saw her parents break up,and them she asks you to fix their relation and there's come the chokerpoint,here you decide if you began this story for Mia or for Helen,becuz after that point,is all about Helen(you already know her,but since the game stops the development with Mia,you begin to see more motives to like Helen),and after all your work and time wasted,you get to choose Helen or Mia...in the end,Mia story doesnt serve to develop her character,it serves to develop her parents story and background,and that's kinda a bummer,Roxxy's story that is just as long as Mia story develop all the characters involved with her,and makes you feel like you acomplished something,even the teachers story,who is way shorter than Mia and Roxxy's story,manage to make you feel like you did acomplished something...however you cannot really say that for Mia story,after all the shit you have to do,the only thing you can feel after that is the feeling of being an overworked mule,a total tool....
