Kyung-ah kills Se-hoon. Hye-jin calls the rest of the group and Jung-wook claims Sun-ae blamed herself for causing Kyung-ah's death, and reveals she went to the U.S. to seek mental treatment, not education. Desperate to escape his job, Hyun-jun blackmails Jung-wook into becoming his lawyer. He hands over a tape showing Jung-wook and Mi-ryeong having sex, recorded by Se-hoon, who had a habit of recording people. Se-hoon also recorded Kyung-ah's death. Hyun-jun is killed next. Hye-jin angrily asks Sun-ae her why Kyung-ah is going after them. Kyung-ah appears, visible only to Sun-ae, who runs away.
