The casting line-up has been confirmed for tvN’s upcoming crime drama Mouse, with Lee Seung-gi (Vagabond), Lee Hee-joon (Mistress), Kyung Su-jin (Train), and Park Joo-hyun (Zombie Detective) in leading roles.

Lee Seung-gi takes on the central role of neighborhood police officer Jung Ba-reum. He is the picture perfect model of good behavior, kindness, and always doing the right thing. And although a little bumbling as a fresh, rookie officer, he is strongly motivated by his passion for justice. However, when he gets assigned to hunting down the infamous serial killer and psychopath who has been terrorizing the nation, he encounters something unlike anything he’s seen before and his life is changed forever.

In contrast to Lee Seung-gi, Lee Hee-joon plays the more hardened police detective Go Moo-chi. Having lost his parents to a serial murderer as a young child, his heart and motivation for being on the police force has always been about revenge. The culprit who killed his parents was imprisoned behind bars and his goal is now to gain access to the prison facility and take the murderer’s life by his own hands.

Kyung Su-jin’s character is PD Choi Hong-joo. Nicknamed “Sherlock Hong-joo,” she mainly produces informative shows about current affairs and culture. She is well accredited for her work and has a collection of awards for journalism and media. But she also carries a secret and trauma from her past, as she was once forced to be an accessory for murder as a child.

Park Joo-hyun plays high school student Oh Bong-yi, who lives alone with her grandmother. She can be bit of a troublemaker due to her tough personality and being skilled in combat sports like martial arts, boxing, and jujitsu. And she has a sibling-like relationship with Lee Seung-gi, always bickering when they see each other.

In supporting roles, Ahn Jae-wook (Five Enough) plays a famous neurologist with Kim Jung-nan (Tale of the Nine Tailed) playing his wife. And Pyo Ji-hoon, a.k.a. P.O. (More Than Friends) plays a junior detective who follows sunbae Lee Hee-joon like a puppy.

Written by Choi Ran (Black) and directed by PD Choi Joon-bae (Come Here and Hug Me), tvN Mouse is currently being planned to air early next year in 2024.
