There was a killer on the loose. A clever one at that. You were assigned the case of this new killer running around town so you got to investigating.

Main suspect? Byun Baekhyun. A very... Unsuspecting guy, you can say. Cute face, nice personality, and all that. But, you knew there was much more behind that facade.

You were taking the train home after working and who did you see? Baekhyun. What a coincidence.
