There are plenty of fascinating characters on Netflix's Squid Game, including Lee Myung-gi (Im Si-wan) and Kim Jun-hee (Jo Yuri), a former couple who both end up playing these terrifying games. Jun-hee has a sad backstory and is now pregnant and in a rough spot thanks to her relationship with Myung-gi. Since Myung-gi is involved in cryptocurrency, Jun-hee lost money, which motivated her to play the Squid Game.
