The math teacher who got fired because of Jae In uncovering the truth tries to retaliate. An appears at the right moment to save Jae In and he continues to stay with her to protect her. However, the secret Jae In wanted to hide from everyone has been revealed and she disappears.

After two years, An and Jae In meet again. Jae In has become a police officer while An doesn’t seem to have made much progress in honing his psychometry skills. While they are both trying to find a kid that went missing, An finds a suspicious suitcase that turns out to have a dead body in. Will the two be able to find the killer?

Seong Mo asks Jae In to help improve An’s psychometric powers. While Jae In hesitates to let An perform a read on her, An realizes that she’s the girl he remembers from long ago. Meanwhile, Dr. Hong identifies the body found in the suitcase, and while following Seong Mo, An meets a mysterious man.

As Seong Mo wished, Jae In promises to help train An’s abilities. As An is discharged from the hospital, he and Jae In start to read books on crimes. To find more information on the real Kang Hee Sook, Ji Soo calls An and Jae In to the autopsy room.

Meanwhile, An and Jae In go on a first date. With his unusual ability, An accidentally finds out that Jae In’s father was the culprit of the arson at Yeongseong Apartment.

An is terribly shocked to know that Jae In’s father was the arsonist of Yeongseong Apartment fire, and he runs away from Jae In. Ji Soo strongly believes that Seong Mo’s mother is still alive and is now living as Kim Song Hee. However, Ji Soo doesn’t understand why Seong Mo keeps it as a secret to her. Meanwhile, the security camera around the security center is down again, and Jae In runs into a suspicious man.
