The tvN drama 'Circle' has revealed the images of cast members and they are seen holding up signs that read as, "When 'Circle' exceeds 3 percent ratings, we will give out coffee to 300 people."

On May 22, the said drama premiered and recorded 2.9 per cent ratings and the second episode gathered 2.3 per cent.

Therefore, the cast which include Yeo Jin Goo, Kim Kang Woo, Gong Seung Yeon, Highlight's Lee Gi Kwang, and An Woo Yeon decided to do something special once the drama hits 3 percent viewership ratings.

According to Soompi, a source from the production team revealed, "The story will become more interesting as the search for the truth officially begins on episode three."

The thriller drama is divided into two parts, "Part 1: Beta Project" and "Part 2: An Amazing New World," and it takes place in 2017 and 2037, respectively. The drama takes place in two timelines but the characters do not move to the present to future or vice-versa, rather two similar stories from two different eras are being told in one episode.

In the upcoming episode's preview, it is seen that Kim Woo Jin (Yeo Jin Goo) and Han Jeong Yeon (Gong Seung Yeon) are at the Handam University of Science and Technology pursuing the serial killing case. On the other hand it is also revealed that Kim Jun Hyuk (Kim Kang Woo) is investigating the "stabilizing care chip" and it's related to memory.
