Our Little Boy

Hunter Tazer and Rain Meadows were that couple in high school that made people stop and think "Damn, are they still together?!" For the two years that they'd been dating, everything was going fine until Rain discovered she was expecting a child. Scared of what Hunter will think, she lies to him about her mother getting a new job so she has to move away to Chicago, just so she doesn't have to tell him about the baby. Instead, she moves across town. With just the help of Dania, Hunter's older sister, Rain manages to raise her son, JJ. But she realizes that he's somewhat different from every other kid. Firstly, he arrived two months early and was perfectly fine. Secondly he has non-stop energy and thirdly he developed his canine teeth before his first ones.
Could Rain eventually find out what's wrong with her little boy on her own? Or will she need to confront Hunter after four years of absence?
