Reading a book is like a person's life is coming to you
Sun Chaek hits the ultimate jackpot, waking up as a fabulously wealthy noblewoman inside a popular romance novel. All she wants is to stay out of the way and enjoy her cushy new life while the fated leads, Lee Bun and Eun Ae, fall in love as planned. Yet destiny seems determined to push her into the spotlight, forcing her directly into the path of the story's central romance. Her perfect life is on the line, and she's not even the hero.
The first night in Yi Beon's life
By chance, Sun Chaek meets Bun and ends up spending the night at his place. The next day, Bun wishes to rush to arrange a wedding with Sun Chaek. But Sun Chaek has no intention of marrying him. She begins plotting clever ways to escape the situation. Will Sun Chaek’s plans succeed? Meanwhile, she finds herself threatened by thugs in the woods. That’s when a mysterious man suddenly appears to help her.
Something always happens under the moonlight
To set her story back on course, Sun Chaek orchestrates a gathering to unite the intense Lord Lee Bun with his intended match. But her elaborate scheme hilariously backfires, only fanning the flames of his dangerous obsession with her instead. Now, she's trapped in a new chapter she never meant to write.
We need Cha Sun Chaek.* (*Means "Plan B")
Bun shocks everyone in the Astral Philosophy Club by announcing that he’s going to marry Sun Chaek. To make matters worse, Bun goes to Sun Chaek’s family and claims that she took his innocence and that is the reason they must get married. However, Sun Chaek’s father firmly opposes the idea.
There Is No Such Thing as ''As It Was''
Resolved to bet her fate on Lee Bun, Sun Chaek bravely enters the treacherous royal bride selection. Just as she commits to her path, Soo Kyum reels from the shocking news that Eun Ae is also a candidate. The game for Lee Bun's heart has just become dangerously complicated.
Playing the Field and a Disguise
Bun gets close to Hwa Sun in order to enter the Do family’s house and snoop around inside to find evidence regarding the foreigner. Meanwhile, Sun Chaek feels lost about how to tackle the assignment given by the Queen Dowager, but after witnessing the struggles of farmers suffering from a bad harvest, she suddenly gets an idea.
The Inflection Point
Lee Bun creates a perfect romantic day for Sun Chaek, proving their love can overcome any obstacle thrown their way. Their fairytale moment is destroyed by the arrival of Lee Kyu, a charismatic stranger who claims a prior right to Sun Chaek's hand. He built a perfect world for her, only for another man to tear it down.
The Shadow that has Returned
While sharing a moment of affection with Lee Bun, Sun Chaek is caught by her father and is promptly grounded. Meanwhile, the King grows suspicious of Lee Kyu's sudden return to Hanyang. Meanwhile, Bun makes every effort to earn the favor of Sun Chaek’s family. Bun’s first target is Sun Chaek’s brothers.
