There's a saying that the scariest haters in the world are the fans.

The manhwa that Hee-ro Lee had been faithfully reading since he was a child, "Adventure King," had come to an unsatisfying conclusion. However, it seemed like the author was one step ahead of the reader in this case. To the rage-fuelled message that Hee-ro had sent in response to the ridiculous ending, the author replied, "Would you like to try?" Then, Hee-ro woke up as a character in Adventure King.

Not all character possessions end up being fortunate, however. The character that Hee-ro's soul had occupied was an extra in volume 1, chapter 1 whose sole purpose was to be used as a benchmark for the strength of the main character, "Leo," then tossed aside. The message that appeared before this Hee-ro now said:

[Take up space on the pages, secure yourself story time, and survive till the end of the story.]

Chances to reappear at 0%, and no abilites or skills! All he has is the knowledge of the whole plot of Adventure King...
