Once rivals in school, two brilliant doctors reunite by chance — each facing life’s worst slump and unexpectedly finding solace in each other.

Songwon Police Violent Crimes Unit 2 has the lowest arrest rate in the country. After their chief is demoted, the team is exiled to a closed daycare center. Enter Yubin, their new leader. Despite the team's initial distrust, Yubin and the team start to bond as they solve cases together.

After a heart-fluttering date, Joonho, a heart surgeon with a perfect smile, and Jisun, a free-spirited teacher-librarian, share a special night. The next day, they meet at a police station with completely different memories. A shocking polygraph result turns their lives upside down.
