20-year old Deok Yi’s quiet small-town life gets exciting when a former University Professor, Hak Kyu, moves in, running from the scandal of a sexual harassment allegation. He works as a literature instructor at a culture center and she works at an old amusement park. Mutual attraction leads the pair into a lusty affair, but when the fall semester begins, Hak Kyu is reinstated at the university and returns to his family in Seoul, leaving Deok Yi behind. She refuses to let the relationship die, and a confrontation between them turns tragic when Hak Kyu’s wife commits suicide. 8 years later, Hak Kyu is a popular writer, but he is barely able to see, losing his eyesight to a disease, and he's estranged from his daughter Cheong, who blames him for her mother's death. At this time, he befriends Se-Jung, a new neighbor who moves in next door. He gladly accepts her help and Cheong becomes romantically attached to her, neither realizing she is in fact Deok Yi, the woman Hak Kyu betrayed 8 years ago, now on a quest to destroy them. Her plan sets off a vengeance-fuelled chain of events that ultimately sets the three bitter, angry and desperate schemers on a twisting collision course with each other.
The story will focus on a love triangle between the three leads. Eikura plays the role of Morimoto Naoko, a girl from the countryside whose first love is her uncle, Ikezawa Masato. She follows after him to Tokyo by getting admitted into an elite medical university, but there she runs into Masato's girlfriend and colleague Aya, a beautiful and intelligent researcher who is the daughter of the university hospital's director. However, things get complicated after Naoko and Masato meet again.
Both stories focus around women seeking revenge for crimes committed against them in the past. Also, Yoo Sun is in both of them, though her role is more major in Eve. Eve has more romance and the main character is keeping more secrets, while Queen of Masks is a more a story about a tangled friend group where everyone has their own lies and love stories going on but is not exactly romantic.
