Her Role in Squid Game 2

In Squid Game 2, Lee Joo-Sil played the onscreen mother of Wi Ha-Joon’s character, Hwang Jun-Ho. Fans will remember Jun-Ho as the dedicated cop from the first season who was on the hunt for his missing older brother, who was revealed to be the Front Man (played by Lee Byung-Hun).

Her powerful scene at the dining table, where she reminisces about her other son and reveals that he once donated his kidney to Jun-Ho, left a strong emotional impact.
