Actor Yoon Namu will make a special appearance in the SBS drama Shin I-rang Law Office.

On the 11th, Yoon’s agency Gram Entertainment confirmed he will guest star in the new Friday–Saturday series Shin I-rang Law Office, which premieres on the 13th. The drama is written by Kim Ga-young and Kang Cheol-gyu and directed by Shin Jung-hoon.

Shin I-rang Law Office centers on Shin I-rang, a lawyer who becomes possessed to deliver satisfying resolutions to the grievances of the dead, and Han Na-hyun, a cold-blooded elite attorney who stakes everything on winning. The series blends oddball charm with warm, revenge-driven adventure.

Yoon Namu plays Jeon Sang-ho, a special client whose possession involving Shin I-rang (played by Yoo Yeon-seok) injects fresh energy into the story. Jeon Sang-ho is a ghost who, in life, was a brilliant scientist; his rational, highly logical temperament defines the role. Yoon’s portrayal promises a strangely compelling and previously unseen take on a ghost, sparking audience curiosity.

Yoon has proven a wide acting range across screens and stages — from TV dramas like Pro Bono and Shin Sajang Project to plays such as Mending the Living, On the Beat, and Showman: The Fourth Double for a Dictator. He consistently transforms himself for each part and delivers layered, three-dimensional performances, so anticipation is high for this cameo.

Yoon’s guest turn in Shin I-rang Law Office premieres on the 13th; the series airs Fridays and Saturdays at 9:50 p.m. on SBS.
