Yasin Craig, the heir to the prestigious Craig family and a special forces soldier, survives a plane crash during his final mission, only to be saved by battlefield doctor Xenia Jones. When Yasin regains consciousness, he has no memory of who he is. Meanwhile, Yuna, who stumbles upon the ring symbolizing Yasin's identity, is determined to secure wealth and status. She deceives Yasin's mother and becomes the adopted daughter of the Craig family. Fearing that Xenia might uncover the truth, Yuna starts to aggressively undermine her. Unable to remember his past, Yasin finds himself protecting Xenia—and in the process, unexpectedly regains his memory.
