Both dramas begin with the FL having her face exchanged with another girl. Both FLs have a mission (revenge vs. saving their sister) which they are determined to accomplish. The MLs are both soldiers and recognize expressions/behavior in the FL, leading them to suspect her true identity. Both couples have a past connection and have never forgotten each other.
