So Ji sub's natural hacking abilities could not be hidden despite his posing as a police officer.
In episode 8 of the SBS drama 'Ghost' aired on June 21st, Yoo Gang Mi (played by Lee Yeon Hee) detected that the cause of the high school murder had been the scholarship, and finally got to have a long rest.
In the bright morning, however, Yoo Gang Mi was abruptly awakened by a loud musical noise in her room. Just like the computers of the victims from episode 3, Yoo Gang Mi's computer became a zombie PC in an instant. A message that read 'stop sleeping' appeared on the screen.
Soon after, Yoo Gang Mi received a text message that read "come out to the café in 5 minutes." This was all a joke from So Ji Sub's hacking. Even while posing as a police officer, So Ji Sub did not hide his playful hacking skills in front of Lee Yeon Hee who knew his secret.
