Back at Blood Free, the news of Ho-seung's death sends shockwaves through the team, with Ja Yoo instructing her assistant, Jung, to extend her condolences to his family. However, Jung's fear and subsequent confession to Geon-u that she plans to flee suggest a deeper betrayal within the ranks of Blood Free. Geon-u's orders for her to stay put reveal a web of espionage that has ensnared both Ja Yoo and her team.

Ja Yoo's visit to Chae Woon in prison and their discussion about the possibilities of who could be the spy, as well as the confirmation that Shin Gu must have been murdered, add another layer to the mystery surrounding Blood Free. Ja Yoo's decision to clear Chae Woon of all murder charges, despite the assault on a police officer, shows her commitment to protecting her team and the integrity of her company.
