Samar, a single mother working as a hotel cleaner, raises her brilliant son Leo all on her own. Six years ago, she shared one night with Julian, heir of the Sterling Group, never knowing who he was. Leo, by a stroke of luck, signs a temporary father-son agreement with Julian—and the DNA test reveals the two are biological father and son. As Samar takes a position as a maid in the Sterling household, she and Julian reunite and feelings quietly bloom, though Chloe's schemes come at her relentlessly. Samar also discovers she is pregnant with twins—and unravels the truth of her origins: she is the eldest daughter of the Holt family, missing for twenty years. Through misunderstandings and reversals, Samar finds her family again and builds a complete, whole family with Julian.
