Lee Jin Woo once lived a dismal life.
He lived pitifully on a day to day basis in his five-pyeon studio filled with mold.

Then, one day, he died in a sudden fire.

When he wakes up, he finds himself inside a novel.
But there’s just one issue…
He had become the novel’s villain!

He was the cold-blooded prince of the Jin country. Decisive and smart, he had looked down on the world with apathy and disdain.

She was his Wang fei, a person who had saved him in the past, but even he wouldn’t look at her.

When the fire raged and death claimed her, it was only then that she realized her existence was nothing but a joke from the beginning.

She opened her eyes once more after spending two years as a roaming, vengeful ghost. In this lifetime, Ye Zhen promises that she will be a different person. With a slight smile, she will ruthlessly trample on those who had schemed against her and lied until her demise!

Most importantly, she would let him experience the pain of an unrequited love; the bitterness of seeking something you cannot obtain!

For He Yi, life was like a coffee table laid with all sorts of coffee mugs resembling her misfortunes. She lost her virtue and had a premarital pregnancy—without knowing the father’s identity—right before her engagement. Her father passed away due to a heart attack when his company wound up. At that point, He Yi’s child was one-month-old and the culprit behind these tragedies was her trusted husband.

Under despair and rage, she drove toward her nemesis to knock him down. That had resulted in her becoming a destitute divorcee who could not afford proper meals after she had finished serving her sentence in prison five years later. She lost everything and her child was snatched away by her nemesis.

Her ex-husband eventually married his mistress who was contemptuous of her. “How are you able to live with this? I’d die much earlier if I were you.”

He Yi only gave a slight cold smile. “The reason I’m still alive is to witness how you go to Hell!”
