In "Doctor Cha Jung-ook," a dangerous crack emerges in the double life of Kim Byung-chul and Myung Se-bin. On May 12, the JTBC weekend drama "Doctor Cha Jung-ook" (directed by Kim Dae-jin and Kim Jung-wook, written by Jung Yeo-rang, produced by Studio&New, SLL, and JCN) captured the chilly atmosphere between Seo In-ho (played by Kim Byung-chul) and Choi Seung-hee (played by Myung Se-bin). Seung-hee's cold demeanor and In-ho's stern face suggest that a major change has occurred between them, creating curiosity and suspense.

In the previous episode, In-ho and Seung-hee's secret relationship was exposed, shocking their family members with the unexpected revelation. The truth also caused trouble for Cha Jung-ook (played by Um Jung-hwa), who had been trying to keep everything under control. Now that she knows about her husband's double life, she, along with Seung-hee, who is determined to fix everything, and Roy Kim (played by Min Woo-hyuk), who is starting to realize his feelings for Jung-ook, have all become unpredictable. The turning point of their complicated relationships is expected to heat up in the latter half of the drama.

Seung-hee's actions at Jung-ook's birthday party, where she appears ready to flip the table, adds to the tension. Meanwhile, the newly revealed meeting between In-ho and Seung-hee on an icy surface raises questions about the changes in Seung-hee's feelings towards In-ho, who seems to be struggling with his emotions. The focus is on the crack that has emerged in their once delicate relationship and what conversations may have taken place between them.
