Lee Hanri is someone that you cannot expect. She loved pink but, she is tough. She speaks softly but she is boyish. She looks friendly and yeah, she is. She smiled but no one know what could lie behind her angelic face. Park Jimin is a newbie in 4SK. He is friendly, and a scaredy cat..especially about ghost and horror story. The first time he comes to the school, he met with Hanri. Coincidencely, they were arranged as seat-partner in the class. Though Hanri seems friendly but he wants to unveil more about her.

He did..but he did not understand why Hanri must dissappear after school? 

One day, he decided to follow her however they were stuck in a maze which either they could die or live.
