Sins of Survival

Kang Sieun is no stranger to hardship. For years, she's lived alone, cut off from her family, and fought to survive in a world that seems determined to break her. With mounting debt and no way out, the Squid Game offers a dangerous but tempting chance to escape her struggles once and for all.

What Sieun doesn't know is that her estranged brother, Kang Daeho, has also entered the game. As the deadly competition rages on, Sieun must face the challenges of the games and decide if she can trust the brother she hasn't seen in years - or if survival will drive them apart for good.
