Baby by the Numbers

Andrea's not ready to give up hope on finding the right one. She doesn't trust herself to spot him, but she won't quit looking. When the police are called again because Andrea's boyfriend decided to put his hands on her, her best friend also shows up to take her home with him. Chase has always been there, even if he's kind of a loser too. Her friend might be a middle school math teacher, but he can charm any woman into bed.
All he dates are model types, unlike the pleasingly plump Andrea. Andrea and Chase have never denied the attraction they felt between them, but they never went beyond intimate kissing. One night together leaves Andrea pregnant, and she's not sure who the daddy is. Chase claims her baby as his, but what happens when her ex starts making threats?
