BtoB's Yook Sung Jae transforms into a stalwart policeman for the upcoming SBS mystery drama, "The Village: Achiara's Secret." On September 24, SBS released photos depicting an interaction between the series lead actors, Yook and Moon Geun Young.

In the teaser photos, the 20-year-old acting idol is depicted in a patrol uniform while Moon sports a conservative outfit consistent with clothing that would be worn by a teacher.

Moon is Kim So Yoon, an English teacher who relocates to the sleepy town of Achiara. She discovers a hidden corpse, which leads to an investigation, in a village that is normally devoid of crime.

Yook portrays Park Woo Jae, a policeman who has the difficult task of solving a mysterious murder involving an unidentified woman.

A report published by the Korean outlet Kyung Hyuang provided insight into teaser still and the production process. According to the article, the photo captures an encounter between Woo Jae and So Yoon. Woo Jae approaches the teacher to probe her for information regarding the deceased woman after her students have walked away.

"The process of how Woo Jae reaches the truth is interesting," said a representative for the production, in a statement published by Kyung Hyuang.

During the shoot, the BtoB member and the seasoned actress rehearsed numerous times to capture the best scene. The spokesperson for the production highlighted the willingness of Moon to work with Yook throughout the filming process.

"Moon Geun Young has the ability to make the other person feel comfortable," said the member of the production team.

Yook appears in his first leading role in "The Village: Achiara's Secret," following his successful portrayal of Gong Tae Kwang in "Who Are You: School 2015." He continues to receive positive attention from K-Drama audiences and critics, who noted his nuanced acting throughout "Who Are You: School 2015," with his character Tae Kwang drawing comparisons to Choi Young Do of "The Heirs."

On September 24, Cube Entertainment expressed their pleasure at his success as an emerging endorsement star.

According to a report published by Money Today, he has appeared in eight ads within the past three months, following "Who Are You: School 2015." This has led to increased attention for BtoB, as he continues to receive top endorsement offers.

"The Village: Achiara's Secret" premieres on October 7, following the conclusion of "Yong Pal."
