The TV drama "Every Night," starring Kim Sun-a and Lee Dong-gun, took over the time slot of the MBC hit production "Lee San" with safe 10% ratings.

According to the ratings research company TNS Media Korea, "Every Night" recorded national ratings of 11.6% for its first episode, which aired on the 23rd.

The ratings were lower than the 14% reached by "Lee San" for its first broadcast last September. However, "Every Night" is up against tough competition.

The same primetime slot is occupied by the SBS TV drama "Le Grand Chef," (16.4%) starring Kim Rae-won, and the KBS 2TV production starring Eric, "Chil-woo, the Mighty" (10.5%). "Every Night" was also at a disadvantage due to a one-week delay of the first episode.

Another ratings research company, AGB Nielson Media Research, found that the TV ratings for "Every Night" were only 10.9% nationwide, while "Le Grand Chef" came in at 15.2% and "Chil-woo, the Mighty" reached 11.1%.

"Every Night" is about Korea's Cultural Heritage, with Kim Sun-a on the task force of Cultural Heritage crime-fighters and Lee Dong-gun playing a flirty art historian.
