Chapter 1: It's not a tutor It's a friend

Normal high school AU of Rubapphire or Rubpphire. Just kidding.
Sapphire gets to tutor a girl who everyone seemed to know as a monster. Is she really that bad? Is she a monster? Will Sapphire get to know her?
Well just read so you can find out.
Also the cover It's not mine so all credits to the artist that I don't know.
