On May 6th, the production team of JTBC's weekend drama "Doctor Cha" (directed by Kim Dae-jin and Kim Jung-wook, written by Jung Yeo-rang, produced by Studio&NEW, SLL, and JCN) released a photo of Cha Jung-suk (played by Um Jung-hwa) captured on the edge of a rooftop.

In the photo, Roy Kim (played by Min Woo-hyuk) is seen tightly embracing Cha Jung-suk in front of Seo In-ho (played by Kim Byung-chul), which arouses curiosity about their relationship. In the previous episode, the relationships among Cha Jung-suk, Seo In-ho, Choi Seung-hee (played by Myung Se-bin), and Roy Kim became unstable.

Choi Seung-hee's meaningful actions of not hiding her dangerous encounters with Seo In-ho, Roy Kim warning him about his double life, and Roy Kim's visit to Cha Jung-suk after setting up a confrontation with Seo In-ho, all heightened the viewers' curiosity.

In the midst of all this, Seo In-ho and Roy Kim's worried __EXPRESSION__s as they gaze in a certain direction catch the eye. There is Cha Jung-suk standing on the rooftop, trying to calm down the patient in a calm manner despite the precarious situation. Roy Kim holding Cha Jung-suk tightly and Seo In-ho's shocked reaction to the sudden turn of events are also intriguing. The focus is on what kind of incident has turned the hospital upside down, including Seo In-ho and Roy Kim.

In episode 7, airing on May 6th, Seo In-ho's jealousy (?) explodes. The production team of "Doctor Cha" stated, "A massive event will bring a decisive change to the relationships among Cha Jung-suk, Seo In-ho, and Roy Kim."
