This was the office setting for Misaeng/Misaeng: Incomplete Life (미생) (tvN, 2014), where a number of floors in the building were used for filming the show, like the garden and the rooftop. Most notably, the entrance of the building was where protagonist Jang Geu-rae (Im Si-wan) used to collect his thoughts, and where he’d also slipped a written reminder for himself between the slots of one of the columns.
Infinity Challenge’s Muhan Company (무한상사, 2016) was apparently also filmed here.
Seoul Square [서울스퀘어] is located in the neighborhood of Hoeyeon-dong [회현동], Seoul. This 23-storey building stands across from the main Seoul station [서울역], and is connected to the station via underground. Aside from offices, it also houses retail and dining options, mostly on 1F and B1F. There is a Misaeng-related exhibition located on B1F of the building, with information pertaining to the show and a display of props used in the show (information correct as of September 2016).
