Lee Jieun has been living in her grandfather's magical workshop for as long as she can remember. Today is her 19th birthday. Ever since her grandfather died, she's been living there alone, not knowing how to get to the outside world; but thats okay for her. She's waiting for someon to wake up, someone who will take her away from the loneliness.

Lee Hyunwoo resides in the room across from Jieun's. He is a creation of her grandfather's, so that he can be her companion when her grandfather passes away... but something has gone wrong in the process, and he will only wake up when Jieun turns 20 years old.
