Mc is a lover of horror amd loves to read creepy pastas. There is one really popular creepy pastas i think amd he goes to the there to buy merch when onw of the event is to get a job class. He gets the most difficult one and somehow ends up in that creepy pastas, now he has a job to go through other popular creepy pastas and no die while earning money
Our mc, kim soleum, is a fan of a popular horror wiki creepypasta which is DER (Darkness Exploration Records). There was a pop up event so as a (hardcore) fan he decided to go. While in there, there was an event using a roulette where the 1st place price is they will get to create their own character from 3 major factions of DER (Feel free to scroll further down if your curious what are the 3 major faction) that will be canonically included on the wiki. Soleum tried it thinking he don't expect much only to win the said 1st price. As he registered himself and got an id from daydream corp as a reward, he got "isekai'd" in the DER universe as an employee at the orientation of Daydream.
Now our dear main character has to WORK in daydream and collect as much and as high dream essence as possible to get a wish ticket and go back home. Yes, he know "all" ghost stories of this world and how to survive and destroy (cuz wits) it but he is a COWARD so yeah.
There are 3 major factions in this DER Universe that is kse can have a chance to win from the roulette.
First faction would be the one he won a prize to which is from the Daydream Corp.. This is where his working at.
Second faction as already mention earlier in this manhwa is the Disaster Management Bureau
!!!SPOILER!!!
The third faction is the Church of the Luminous Unknown which would be introduce much much much later on this manhwa.
Yes, they can be considered as "fictional" people to the mc as some of the characters were mentioned previous times by the wiki, but because how human they are, the mc doesnt consider them just as a fictional chracter but a living breathing human being same as him.
As for the Daydream Inc, theyre not exactly a creepy pasta story, but more of a group that is part of the story. Take example: Fnaf entertainment, Playtime co. from Poppy playtime, or even SCP foundation- although all three are companies from a franchise that are involved with the story, the company itself IS NOT a creepypasta ghost story

Can someone explain the gist/ summary of this? I tried reading chapter 1 but im still confused so its not as enjoyable
