Sol is short of Soloman. He has been your ex-boyfriend for 4 years now. You never heard of him since the break up and you focus on your career for 4 years and now you're officially a pediatric nurse. Meanwhile Sol also focuses on his career to be a Pediatrician Doctor.

You're minding your own business, taking care of the sick kid as usual when a doctor came into the room it was Sol. Obviously he was shocked but he tried acting professional. "Are you done now nurse?"
