A freewheeling story. This is a novel that the author and readers write together, so don't hold back. Leave lots of comments.
(Or you could call it a game we play together.)
(That's also why I'll only start writing once the story has at least 20 favorites. The author is afraid there won't be enough readers to participate and the story won't be able to progress.)
[Blurb One]
There's a detective agency called "W Family Investigations."
They say that as long as the money is right, there's no case they won't take.
"Boss, I need you to investigate something."
"What is it? Tell me the details."
"Everyone at my company seems to have gone crazy! I'm terrified to go to work! I want you to fill in for me for a few days and investigate while you're at it. I just want to know if something's wrong. If there is, I'll quit. If not... I'll go see a doctor."
"That sounds kind of dangerous. I won't take it for cheap."
"Two hundred thousand! I'll pay you two hundred thousand either way!"
"Twenty thousand if nothing's wrong, two million if there is. Take it or leave it."
[Blurb Two]
One day, strange events began appearing all over the world.
Scientists detected the reawakening of a mysterious energy.
There are only two possible outcomes for those who come into contact with it: 99% die, while 1% gain extraordinary abilities.

Reading guide:
1. Very little romance [because I really can't write it, so I gave up], but there is a male lead.
2. Readers can influence what the characters do to a certain extent [just comment "character name + action". If lots of people suggest something, I'll go with the most popular choice].
3. Lovecraftian horror + exploration and puzzle-solving + a small group leveling up.
4. Lots of original worldbuilding. Don't overanalyze it.
Theme: Readers should get involved, too!
