Soomi is your normal average girl next door, she may look fine and always cheerful. But when the night caves in and she is alone with her aunt at home, she is always ordered around and abused too. She hides her scars and marks under her clothing and puts on makeup over her scars on her cheeks. 

"Never judge a person by their looks." Is what humans tell humans, but we humans still judge people easily.

"It hurts how a person can just walk into your life and take all your kindness away and just walk out of it, like nothing happened." 

Yes this is a sad and cruel world. And she, Lee Soomi knows that cruel world too well she fell off the 4th floor of her apartment. 

In result, she lives on because she landed well on a flower bed, but when she woke up she got her wish. Not a fully granted wish, she didn't die and go to heaven as she hope. Instead she got a sickness of loss memory. Amnesia.

Now, she's retrieving her memories step by step. Retracing her memories, one by one. Trying to forget painful memories and creating new happier ones. But, memories, even the most painful memories can never be erase. It will always come back. 

Memories are never gone, just forgotten.
