Jang Yi-jung

In-young, a high school student who is alone due to her parents' sudden death, is forced out because of her overdue rent and stays hidden in the Korean Dance Art Troupe where she belongs. In-young, who is still living bravely and brightly despite the sad situation, is caught by the director of the art troupe who is known for being rough, and the director who could not put In-young in the art troupe eventually begins to live with her.

Jae-hyuk was once a star detective in the regional investigation unit, but after losing his marriage and missing promotions, he's now a washed-up small-town cop whose life has completely fallen apart. His new partner is Jung-ho, a rookie detective and former influencer armed with sharp intelligence, ambition, money, and youth. The mismatched duo doesn't click at all, but one day they arrest a thief who stole from a church donation box and discover he's a prime suspect in a Gangnam murder case. However, the case has already been closed with another perpetrator arrested. To catch the real killer, they head to Seoul on a business trip. With prosecutor Mi-ju's promise to support are investigation, they request cooperation from Gangnam Police Station. But their questionable teamwork - or is it team-killing? - puts the case in jeopardy.
