Both drama feature Ham Eun Jung in leading roles and share common themes of family drama, romantic entanglements, revenge, and corporate conflict, all presented through an emotionally intense melodramatic style.
Both are long form family drama that revolve around secrets within a family, and their attempts to deal with their pasts, and the choices they are making and the strain that result from them.
Both explore obsessive love, marriage, loyalty, friendship, betrayal and infidelity. Love Twist strikes me as looking to be a little more nuanced with it's villainous characters; and also created in me a greater level of discomfort offending my sensibilities.
