One day, SSS-rank guide Seon Hee-jae steps onto an unknown snowy field. The person he encounters there is none other than the esper Ha Se-hyeon. "Hyung, Se-hyeon hyung! Wake up, do you know who I am?"

After guiding the collapsed Se-hyeon, Hee-jae himself loses consciousness. When he regains awareness, it's not Se-hyeon but "Kailus" who stands before him.

Realizing he's been transported into the world of his favorite fanfiction "Under the Goddess's Star," Hee-jae follows the instructions of a mysterious blue window that appears.

[Translator] Purify Kailus, or in your world's terms, it would be 'guiding.' Guide him and give him peace. Transform him from the 'Harbinger of Doom' to the 'Guardian of the World.'

The translator claims that just as Hee-jae is Ren Snow from the novel, Se-hyeon is Kailus.
Frustrated by Kailus' unwillingness to cooperate...

"Didn't you want the purification?"
Kailus's fingers traced down his neck, brushing against the silver thread. Hee-jae's eyelashes fluttered at the touch.
"Isn't this what you wanted so badly?"
