A landlady catches her cheating boyfriend in the act, loses her memory after an accident, and mistakes the heir who hit her with his car for the childhood savior she has always loved. To avoid family matchmaking, he hides his CEO identity and agrees to a flash marriage, beginning a supposedly poor life with her in a shabby rental home. As old lovers and scheming rivals try to tear them apart, he protects her from the shadows—until her memory returns and she realizes the poor husband beside her was her true first love all along.
