Attention is being focused on Jang Won Young's older sister, Jang Da Ah, who is officially making her debut as an actress through the drama 'Pyramid Game.'

Ever since Jang Da Ah's casting was announced for the drama, she has been the focus of considerable attention, especially after it was revealed that she is Jang Won Young's older sister.

With the premiere date drawing near, additional trailers for the drama have been released, sparking a divided reaction among Korean netizens regarding Jang Da Ah's portrayal of her character in the trailers.

In particular, many netizens are divided about Jang Da Ah's facial expression when speaking. While some say that Jang Da Ah's acting is pretty good, many have pointed out that her mouth movement is somewhat awkward and weird.

Korean netizens commented, "I think her acting is better than the other actors who can't act," "I think her pronunciation and enunciation are good," "I think she's doing fine," "I think her acting is good," and, "I think her voice intonation is good but it's her mouth that looks awkward. It looked awkward when she was modeling too."

Other netizens also commented, "Her mouth is really weird when she speaks," "Her mouth is definitely really awkward," "She blinks a lot too," "I think she looks awkward because she's a rookie. I guess it'll improve with time," and "Her mouth movement  just needs work lol."

Meanwhile, 'Pyramid Game,' which is based on a popular webtoon series of the same name, depicts a cruel survival rank war where students, divided into victims, perpetrators, and bystanders, immerse themselves in violence through monthly secret voting to select the outcast.

The drama is set to premiere on February 29.
