I am not done with this story yet, but here is some description about it. 

This story will be about a wondering spirit, Baekhyun who was in coma for two and a half years. In these years, Baekhyun followed a man of his age, Chanyeol whom his spirit saw during the accident on the zebra cross. As well as accompanying Chanyeol, Baekhyun searched everyday for his true life and body as he couldn't remember anything. 

Two years and a half had passed, when Baekhyun finally saw his body lying on the hospital bed in a hospital near his apartment. With this, Baekhyun then came to live and could continue his life again after a month of medication. After being completely cured, Baekhyun went to a new school where he met Chanyeol, and this is when Chanyeol realized that the wondering spirit that used to stay with him was gone. Not only Chanyeol, Baekhyun also met Sehun, who used to be a wondering spirit too a year ago. 

This story will cover what will happen next, on the way to 180.
