“Another Oh Hae-young,” tvN’s 16-episode TV drama series, keeps outdoing its previous viewership ratings.

The show is a romantic comedy about Oh Hae-young (Seo Hyun-jin), who is stressed out by a seemingly ideal type of woman with the same name (Jeon Hye-bin) from the same high school who becomes a team leader at the same company.

The drama series began with a meager 2 percent viewership rating when the first episode aired on May 2. As it aroused the empathy of viewers suffering from inferiority complex, the ratings steadily rose to 4.25 percent for its fourth episode on May 10, and 5.03 percent for its fifth episode on Monday, according to media research company AGB Nielsen.

As the viewership ratings have jumped beyond 3 percent, three viewers of the TV drama will be invited to the filming site, in keeping with a promise the main cast made at a press conference on April 22.

They had originally promised to invite fans to the jail where Lee Jae-yoon was filming at that time, but they altered the promise as the jail scenes have already been completed, Mun Jung-hyuk said at Monday’s press conference.

Actress Jeon also made another promise. When the series reaches 10 percent in viewership ratings, “We will invite a fan to be the girlfriend of Park Do-kyoung (Mun Jung-hyuk) for a day,” Jeon said.

“Another Oh Hae-young” airs on tvN at 11 p.m. on Mondays and Tuesdays.
