The SEOUL METRO Detectives are given task to catch a notorious hacker that goes by the name '2K' and there is Byun Baekhyun the respected detective of SMD. Being a respected one, this skilled shooter is very damn snobbish and fussy...until the ordinary Soojin comes to be his partner for the case.

Both of them cannot stand each other, but what would they confess during investigating the case? It might be something sincere..from their heart...
