The science teacher

Rebecca is just a regular ordinary 17 year old girl who lives with her best friend,Jackie, who is also 17 but is just about a month older then Rebecca is. Jackie and Rebecca have known each other for as long as they can remember and they are both in the same high school together, and also have just about most of their classes together. One week, both Jackie and Rebecca go to the next class as the bell rang saying it was time to switch classes. Every time that they both would come to school, their science teacher would be acting strange around Rebecca and Rebecca's ex boyfriend wants her back! Poor Jackie and Rebecca have to go through this all year long and try to back out and ignore it all. Since Jackie is the oldest, she has to help take care of Rebecca while Rebecca is still being responsible for herself. And since they have known each other for that long, Jackie and Rebecca r like big sister and little sister. Will Rebecca make it through the rest of the year without causing trubl?
