  • Role: The female lead (FL), the Saint of Pereshte, and the wife of the Duke of the North.
  • First Life: She married the cold-blooded Duke and, believing her daughter Catherine was ill, sacrificed her own eyesight to heal her. Her blindness, however, led to her discovering the devastating truth: her husband was cheating, and the daughter she sacrificed for was not hers. She was killed after this revelation.
  • Second Life: She regresses to the past, before the tragedy, determined to find her real daughter, Icell, and exact a ruthless revenge on her betrayers.
• The Fake Daughter: Catherine
  • Role: The child Diana believed was her daughter, and the illegitimate child of the Duke and the Mistress.
  • Controversy: Catherine is often portrayed as complicit in the abuse of Diana's real daughter in the first timeline, leading to discussions among fans about whether her ultimate fate is justified, considering she was manipulated from a young age (around 8-10 years old).
• The Real Daughter: Icell
  • Role: Diana's biological daughter, who was swapped at birth and grew up in difficult circumstances.
  • Second Life Goal: Diana's primary mission is to locate Icell and give her the life and love she was denied in the first timeline.
• The Cheating Husband: The Duke of the North
  • Role: Diana's husband and the father of Catherine.

  • Crime: The architect of the baby swap, replacing Diana's child with her own, and a major target of Diana's second-life revenge.

The Core Betrayal: How the Baby Swap Unfolded

The central premise that fuels the entire narrative is the shocking baby swap, a cold-blooded act of calculated cruelty that destroys Diana's first life. The deception was a joint effort between her husband, the Duke, and her supposed best friend, the mistress.

In the first timeline, Diana, a figure of great purity and power known as the Saint of Pereshte, genuinely loved the Duke and their daughter, Catherine. When Catherine's eyesight failed, Diana willingly performed a sacrificial ritual, trading her own vision for her daughter's sight.

The irony is heartbreaking: the act of becoming blind was the very thing that allowed Diana to perceive the truth hidden in plain sight. Her husband and best friend, believing her incapacitated, became careless, and Diana eventually learned that Catherine was their illegitimate child, having been swapped with her real daughter at birth. This revelation led to her death, triggering the story's "regression" element.

Armed with this agonizing knowledge, the Diana of the second timeline is a completely different woman. She is cold, strategic, and focused solely on two goals: securing her real daughter's safety and executing a perfect, devastating revenge against every person who wronged her. The story becomes a thrilling cat-and-mouse game where Diana manipulates events to expose the truth publicly and strip her betrayers of everything they hold dear.

The 5 Biggest Shocking Reveals and Thematic Elements

She Wasn't My Daughter is a popular Manhwa because it doesn't shy away from dramatic, satisfying payoffs. The following are the most critical plot points and thematic elements that keep readers hooked:

1. The Public Exposure at the Debutante Ball

Diana's revenge culminates in a grand, public spectacle. Instead of a quiet confrontation, Diana chooses the most embarrassing and reputation-destroying moment: Catherine’s debutante ball. It is here that she drops the truth like a bomb, revealing that Catherine is not her daughter and that the Duke and the mistress conspired to swap the babies. This public shaming is a key component of the Manhwa's appeal, satisfying the reader's desire for justice served in the most humiliating way possible.

2. The Fate of the Cheaters: A Taste of Their Own Medicine

The ending of the novel (and subsequently the Manhwa) delivers a harsh, yet narratively satisfying, form of poetic justice. The mistress is forced to live out the tragic first life of Diana, losing her own eyes and being abandoned by the Duke. The Duke himself is disgraced, losing his title and power. This 'eye for an eye' resolution is a powerful theme in many revenge stories, and *She Wasn't My Daughter* executes it with brutal efficiency.

3. The Redemption of Icell: Finding the Real Daughter

In her second life, Diana's priority is Icell, her true daughter. Icell, having grown up without the privileges of the Dukedom, is the innocent victim of the swap. Diana's journey to find, protect, and shower Icell with love forms the emotional core of the Manhwa. The story ultimately becomes a tale of a mother's fierce, protective love triumphing over all the machinations of her enemies.

4. The Controversial Character of Catherine

One of the most debated topics among fans is the treatment of Catherine, the fake daughter. In the first timeline, Catherine is shown to have known the truth and even participated in the abuse of Icell and Diana. However, many readers argue that she was a child (around 8-10) who was manipulated and brainwashed by her biological parents (the Duke and the mistress). This moral ambiguity—whether a child, even a complicit one, deserves such a harsh fate—adds a layer of complexity and controversy to what would otherwise be a straightforward revenge story.

5. Themes of Regression and Maternal Love

The Manhwa firmly establishes itself within the popular "regression" sub-genre, where the protagonist returns to a past point in time to change their future. However, unlike many *Otome Isekai* stories that focus on romance or political maneuvering, *She Wasn't My Daughter* centers on the primal theme of maternal love. Diana's motivation is not a new love interest or a better title, but the desperate need to save her real daughter and punish those who stole her life. This focus on fierce, protective motherhood is what makes the story resonate so strongly with its audience.

Topical Authority: Why This Manhwa Resonates

She Wasn't My Daughter is a prime example of the "revenge fantasy" sub-genre prevalent in Korean Webtoons and novels. It taps directly into the reader's wish for justice against overwhelming betrayal. The combination of high-stakes nobility settings, a powerful female lead (Diana is a Saint, giving her innate power), and the deeply personal nature of the betrayal (husband, best friend, and child) creates a narrative that is both addictive and cathartic.

The manhwa’s stunning artwork and fast-paced adaptation from the novel ensure that the dramatic reveals land with maximum impact. It stands alongside other popular revenge Manhwas by offering a protagonist who is not just a victim, but a formidable player who uses her second chance to dismantle the lives of her oppressors piece by piece. For fans of intense drama, moral complexity, and ultimate vindication, this story is a must-read. The journey of Diana le Pereshte from a blinded, betrayed saint to a strategic, vengeful mother is a satisfying arc that cements this title as a benchmark in the genre.
