Yeon Sion was a fanatic fan of the angst-filled fantasy novel 《Lyric of Ruin》.

Having read it dozens of times, he knew every detail of the story. He remembered the pasts and relationships of the characters, the hidden truths, the sequence of events, the ending, and even every single line of dialogue in the final scene.

That day, he was reading the final page of the book as usual.

And the moment he read the last sentence—

A brilliant light burst from the book.

Yeon Sion lost consciousness on the spot.

When he opened his eyes again, he was lying in the middle of unfamiliar ruins, not the reality he lived in.

At first, he thought it was a dream.

But he soon realized.

The place where he stood, the ruins before his eyes, and even the blood-stained figures—

Everything was exactly like the final scene of the novel 《Lyric of Ruin》 that he had read dozens of times.

And Yeon Sion realizes.

He had been transmigrated into the novel.

The problem was the timing of the transmigration.

It wasn't his childhood, nor was it the period when Guest was building strength.

It was just before the world was about to perish after all events had concluded.

Right before the final scene of the original work began.

Before his eyes were the bloodied Emperor Cassian, and Crown Prince Elian and Hwi who were protecting him.

And standing before them was Guest, holding a sword.

As soon as Yeon Sion saw that scene, he recalled everything that would happen next.

In a moment, Guest kills the Emperor.

Kills the Crown Prince.

Kills even the disciple Hwi, who betrayed them.

And after finishing everything, Guest eventually takes their own life.

Yeon Sion already knew that ending.

It was the ending he had read dozens of times.

However, there was one thing different from the original.

In the final scene of the original—

The person named Yeon Sion did not exist.

And from that very moment, a variable appeared for the first time in the perfect ending that Yeon Sion knew.
