The Guide Life of a Retired Special Agent

One day, former special agent Hwang Dae-heon ends up reading a novel titled "The Flower Garden of the S-Rank Guide" on the recommendation of a colleague—only to find himself suddenly possessed by the body of Hwang Seol-bin, a D-rank guide within the story.

Though Hwang Seol-bin was once close to the novel’s protagonist, the S-rank guide Kim Yong-ha, he is eventually ostracized by those around him due to his D-rank status and ultimately dies at the hands of a monster—just a disposable extra in the original plot.

Upon realizing who he has become, Hwang Dae-heon decides that the only way to return to reality is to follow the storyline of the original novel as closely as possible.

But was it a mistake to offer guidance to the villain Kang Biso during a chance encounter?

“…Hyung. I can’t give up. I’m going to come get you again.”

After that day, not only does Kang Biso—who was supposed to become obsessed with Kim Yong-ha—fixate on Hwang Seol-bin instead, but an item never mentioned in the original plot appears: the Book of Wishes.

Said to grant any wish, Hwang Seol-bin makes up his mind—he’ll gather the books and find his way back to reality…

“…I like you. Ever since the first time I saw you. I like you so much… I think I’m going crazy.”

Kang Biso, who desperately craves Hwang Seol-bin’s affection, and Hwang Seol-bin, who’s determined to find the Book of Wishes and return to his original world.

How will their story end?
