For fifteen years, underworld boss Stalin has been obsessively searching for the "guiding light" from his childhood—the person who once saved him. Misled by half of a crescent-moon necklace, he mistakenly identifies the manipulative Yvonne as his savior, cherishing her above all else. Through a carefully orchestrated accident, a blind girl named Luna becomes pregnant and is forced into marriage with the Stalin family—viewed by everyone around her as nothing more than a "breeding tool" clinging to a wealthy, powerful dynasty. Stalin treats his blind wife with utter coldness and humiliation, lavishing all his tenderness and favoritism upon the woman he believes to be his long-lost savior. Little does he know that the very woman he tramples beneath his feet is, in fact, the true light he has spent half his life seeking. Meanwhile, due to her blindness, Luna fails to recognize that Stalin is the same boy she once helped on the streets so long ago. When the truth is finally laid bare, a crushing, profound remorse washes over him—but Luna, her heart shattered beyond repair, has no desire to ever look back.
