Synopsis

After facing death and going back in time, the second marriage to her ex-husband was for the sole purpose of getting pregnant.
Her only hope in an unhappy marriage, the child she gave birth to with her cold hearted husband. Her first life, which was only focused on that child, ended at the hands of an unknown assailant.
‘If I could go back in time, I wouldn’t love him.’
Thus, in her second life, which she miraculously obtained, she chose to marry him with the sole intention of meeting her child again, unlike her previous life, which longed for love.
“Just stay married to me for a year.”
In return, she would cooperate in his investigation on a secrets incident that happened over 10 years ago as he wished.
She thought they were just a married couple in name only, bound by a contract.
“There’s no need to spend the first night together.” She stated.
“But I want to.”
He was acting different from her past life.
***
I thought I would quietly leave as soon as I had a child. But I couldn’t help but say it when I saw his mistress in this life as well.
“That woman, she’s the woman you love.”
The answer to the words I spoke to prevent a repetition of the evil fate of my previous life was unexpected.
“Until this contract is over, you are my wife.”
“…”
“I’m doing all of that only with you.”
Seeing him reveal a creepy obsession for some reason, I pushed myself to gather my thoughts.
Don’t forget, Blair.
He doesn’t love you.
So in this life…
I’ll leave you first.

Editor's Note

⚠️ A Deep Dive into "Regret-Core" Angst. This novel is for readers who enjoy the "Second Chance" trope where the focus is on motherhood and redemption rather than pure revenge. It is heavy on emotional turmoil and the complicated nature of loving someone who failed you in another life.

The "Motherhood" Motivation. Unlike many transmigration leads who seek power or wealth, Blair’s entire drive is her son, Asiel. This makes her decisions—even the controversial ones—feel grounded in a specific, sacrificial logic.

The Redemption Arc. The ML, Herdin, begins as a classic "cold duke" archetype with a history of neglect. His path to redemption is long and involves unearthing secrets about the past that clarify (though not necessarily excuse) his previous behavior.

Trope Alert. Expect the classic "Mistress" misunderstanding, a "Contract Marriage" with a one-year limit, and a significant shift in power dynamics as the MC detaches emotionally while the ML grows increasingly obsessed.

162 chapters + 8 side stories. Completed. A gripping, angsty journey for fans of "The Broken Ring" or "How to Get My Husband on My Side."

Experience Curve

The Regression Cycle
The First Life (The Tragedy): ⭐⭐ – Briefly established as a nightmare of neglect, infidelity, and an untimely death. It serves as the emotional fuel for everything that follows.

The Contract Period: ⭐⭐⭐⭐ – The "cat and mouse" game. Blair is clinical and distant, while Herdin is confused by her sudden change in personality. The tension here is the story's strongest point.

The Truth & Resolution: ⭐⭐⭐ – Conspiracies involving the Temple and the Emperor come to light. The story shifts from a domestic drama to a larger political mystery as the "unknown assailant" from the first life is revealed.

WebNovelDB Review

8 /10

While it follows a generic blueprint, the emotional weight of Blair's longing for her child gives the story an "organic" feel that keeps you clicking through the chapters.

Angst Levels: 9/10. If you want to feel frustrated and then slowly vindicated, this hits the spot. The "push and pull" between the leads is intense.

FL Strength: 7/10. She isn't a "girl boss" in the traditional sense, but her mental fortitude and singular focus on her goal make her a compelling protagonist.

Romance: 6/10. It's a "scars and all" kind of love. It’s messy, complicated, and requires a lot of forgiveness that some readers might find difficult to grant.

Pacing: 8/10. The story moves quickly through the contract phase and doesn't linger too long on repetitive misunderstandings.

The Good: The narrative changes are handled well, and the secondary male lead, Mikhail, adds a genuine layer of "what if" that enriches the drama.

The Bad: Some side villains lack depth and are "evil for the sake of being evil." The ending can feel a bit rushed as it tries to tie up several magical and political threads at once.

The Archetype: The "Relentless Mother." She is willing to walk back into a burning building (her marriage) just to save the one person she loves.

The Final Verdict: A solid read for those who enjoy the "Obsessive ML" and "Regretful Husband" tropes. It’s a rollercoaster of emotions that ultimately rewards the reader with a hard-won happy ending.
