Who is the real barcode serial killer? Before I continue sharing highlights and short recap, I have this nagging feeling as I watch the episode that the real bar code killer could not be this doctor. Chun Baek Gyeong Maybe because it is becoming too obvious that the writer and the story want to point at him at every turn. His presence and his mysterious interest towards Cho Rim is really suspicious but how about Joo Ma Ri's boyfriend, the chef? Kwon Jae Hee It was revealed that no one knew he was the boyfriend. Why make it a secret? Besides, the built of this chef is more closer to the killer Eun Seol met at her parent's house that tragic day. I think Doctor Chun is taller compare to the real bar code killer. Hmmmm....what's the relationship between Chef Kwon and Doctor Chun? Kwon Jae Hee introduced Joo Ma Ri to Doctor Chun. And even if detectives are suspicious of the doctor, Kwon Jae Hee is not even the least worried or suspicious about it...
