Remember about the incident where Kim Jung Hyun showed cold expression during the press conference of “Time”? The Korean media now called such behavior the 'Kim Jung-hyun Disease'.
Some managers said that they have ordered their actors or actresses to not show long faces during the press conference following the Kim Jung-hyun incident.
As compared to the “Time” actor, Yang Se-jong from the upcoming drama “30 but 17” was smiling happily during the press conference.
