Cha-il narrows down the suspects and eventually tracks down the food poisoning culprit. Meanwhile, Se-woong, the current president of JU Construction, becomes sensitive due to the upcoming demonstration of J-BIMS, a project he worked hard to achieve. Amidst the affairs, Yoon-woo from the research department attempts to set himself on fire in the lobby of JU Construction.

Han-soo learns the shocking details of Yoon-woo's self-immolation attempt and starts to suspect that Mr. Park might be trying to leak J-BIMS technology. With the sneak preview event just around the corner, Se-woong has ordered that no disturbances occur before the preview, leading to a suspension of the investigation. Despite this, Cha-il's keen intuition brings him closer to uncovering truths that others have overlooked.

Cha-il successfully identifies the criminal responsible for the technology leak during the preview. However, an unexpected turn of events causes even greater damage to JU Construction. As the situation spirals out of control, Se-woong's position within the company becomes increasingly precarious. Before the leak incident can be resolved, another issue arises concerning unfair hiring practices at JU Construction, with some familiar faces potentially at the center of this controversy.
