The female protagonist, who had gradually established herself as a powerful figure and was saving a considerable amount of money each day, began to feel that this life was coming to an end. Then, one night, as she was slowly waiting for an opportunity, she heard someone's voice and hers from behind the vast moonlit assassin's quarters.

"Around the 17th, kill the new king who will ascend to the throne."
"If successful, you will receive a huge amount of gold and silver treasures.
"I will reward you as much as you want."
...is a serious and equally terrifying order.
But for the heroine, who was trying to end this life, it was a sweet request. The guilt she felt for killing people was all she could shed with tears far greater than any other feeling. Ultimately, she accepted the order.
After becoming an assassin, the heroine, who had been living isolated from the world, only thought about "How can I kill the new king who is about to ascend to the throne?" She had become so insensitive to killing people that she didn't even know who it was. All she thought about was receiving this enormous amount of gold and silver treasure and leaving this place.
Meanwhile, someone was watching the female protagonist. After observing her every move, he quickly ran off somewhere. "Boss." A deep voice reached the ears of the person called the boss.
"Did you check?"
"I checked. It was no different from usual."
"I see."
"...may I ask why you are asking her to do this?"
"That child has interacted with the palace frequently since ancient times, so he knows its geography better than anyone else. He is the most suitable person to complete the mission by navigating the complex palace. If he were to stab the king's heart, it would be a great shock to this country."

"Taking advantage of the chaos, they staged a coup,"Take power."
"That's our goal."
After the leader's words, they were silent. This was all a coup plot hatched by the leader and his assassins. And the female protagonist had fallen prey to this plan.
For one, two, three days... the assassins remained silent. They simply counted the days until the king's coronation, which was just around the corner, and hoped the female protagonist would quickly slice open the king's heart.
The female protagonist, unaware of the plan, simply focused on training for sharp swordsmanship every day with unfocused eyes.
Without even dreaming about what would happen to you.

As the coronation day approached, Yeoju headed to the palace at dawn. She carefully took each step, keeping her most prized dagger, the first she'd ever received, hidden tightly in her sleeve.

After groping my way over the high, thick wall that seemed to pierce the sky, I quietly searched the quiet corridors, holding my breath, as if even a mouse would be detected, to find the King's bedroom. It was now 9:00 AM, and with less than an hour left until the coronation ceremony began at 10:00 AM, Yeoju's steps became more urgent. It was not easy to easily find the bedroom in my memory amidst all the ornate decorations, so I picked up my pace a little faster.
Creak_ A loud noise rang out from the wooden plank where the heroine had stepped, reaching the soldiers' ears. The moment the heroine, whose body had frozen for a moment, began to assess the situation, many footsteps began to be heard, and she looked for a place to hide, but finding a place to hide in the open hallway with no real space was not easy.
"Who is it!!!"
"..."
"...what."
The moment the soldiers rushed in, the hallway, despite their heavy breathing, was empty. The soldiers, suspicious, briefly searched the area, but when they turned around, thinking it might be the sound of a rat, the heroine, barely hanging on to the ceiling, breathed a sigh of relief. A few minutes later, when the guards began to relax, she cautiously lowered herself back to the floor and began to move even faster.
Quietly, but quickly. She paused as she searched the entire palace. At the very end of a long corridor, a particularly gleaming and magnificent door led to the king's chambers.

After arriving at the familiar door, the heroine let out a small sigh before her final act. After calming her heart that was pounding like it was going to burst, she opened the door and aimed her sword at the king's heart that was being prepared.

Phew-
In an instant, the dagger struck its target with precision, and then, momentarily, the strength drained away, causing the sword to drop with a thud. A sense of relief washed over her, as if it were the end, and at the same time, the king collapsed helplessly with a thud. The female protagonist, eager to see his face for the last time, checked his face.
She was in shock.
"You... why did you..."
"...Uh, uh..."
"Oh, no... Hey...!! Wake up!!!"
The king who was scheduled to ascend to the throne today.
"no...!!!!!!"
I never thought it would be my friend, the Crown Prince.
