There are many things that people forget from their childhood.

However, it is odd that one completely forgets a five year time period in their life.

Jung Jessica does not remember what hapened to her from the age of eight to thirteen. As hard as she tries, it's a complete blank. 

Her parents also seem reluctant to fill her in on her missing memories and reassure her that she herself did not go through any accidents that would provoke amnesia. 

But Jessica knows she forgotten something, she just does know what exactly it was.

Or...

Who it was.
