In first episode, we found out that our female lead, Eun Hye, is a con artist on the run from the police after her partner conned her. So to hunt him down, she planned to go after his son for his whereabout. But on the way there, the bus she was on got into an accident. She survived the crash and assumed the identity of a special need teacher who had a same name as her.
When Eun Hye woke up in the hospital, she had planned to disapper from there without attracting any attention. But, it was ruined by Ha Ru, a student from a special need school. He believed that she was their new teacher and wouldn't let her leave. Although being trapped, she continue her hunt. And, when she found out that Ha Ru was her partner's son, she stayed on as the substitute teacher to gather more info on her partner.
The first episode is pretty good in establishing the characters. Eun Hye, although being a con artist, has the heart of a gold. She geniunely cares for ppl. (Which might explains her downfall as a con artist.) Dong Jae is a young, rich, and skilled doctor. But, his scientific curiosity and need for fame and fortune pushes him to take whatever measure to accomplish his goals. Ha Ru is a 27 year old man with mental retardation. He lives in a world where he is happy and eager to please. Now, we already have our cheater, manipulator, and our victim.
