As the doll swung its fist toward the isolation room’s outer wall, the entire institute shook as if hit by an earthquake.

I lost my balance due to the unfamiliar and sudden tremor.

"Sister Seoa! Are you okay?"

With Oh Yerin’s help, I got back on my feet, only to be met by an eerie laughter that echoed through the room.

Cackle, cackle.

Inside the isolation room, the doll was now causing havoc, its size unmistakably larger than before.

Anyone could see that something was seriously wrong with the Theme Park Invitation Doll now.

The doll, which had previously been about 1 meter tall, had grown into a massive 3-meter giant.

"Director Sehee, if this continues, it will be beyond our control. If that doll grows beyond 10 meters, our institute’s isolation room won’t be able to contain it."

"Ugh, what a headache. Was it a mistake to hastily send in those death row inmates?"

The doll had started growing immediately after the inmates were introduced, and as it surpassed 2 meters, it began to rampage.

"It’s okay. The Reaper will surely handle it somehow!"

While everyone else wore grave expressions in response to the Object’s rampage, Researcher Oh Yerin remained cheerful.

I’m seriously beginning to think we need to investigate whether the Gray Reaper has some sort of mind-altering ability...

Cackle, cackle.

Something strange began emerging from the doll’s mouth.

Blood-soaked, severed fingers.

The Theme Park Invitation Doll was now spewing blood and pieces of human flesh from its mouth.

Chunks of mangled flesh and severed fingers spilled out uncontrollably.

"Oh? I think I’ve seen that ring on one of those fingers before!"

Researcher Oh Yerin pointed at a finger on the floor.

"It looks like it belonged to that big guy with the timid expression."

Fortunately, after vomiting a torrent of blood, the doll’s growth seemed to stop.

"This is bad. If that thing grows every time an inmate dies, the institute won’t be able to handle it."

"If it grows 2 meters per person, it could potentially reach up to 18 meters."

Even under generous assumptions, the isolation room’s walls could barely withstand a 10-meter tall doll, so we urgently needed to devise a contingency plan for a containment failure.

"Reaper! Hurry up and tear your way out of there."

But Director Sehee didn’t seem to be taking the situation seriously.

I’m really starting to believe the Gray Reaper has some sort of mind-altering ability...

I woke up on a bed that was so comfortable it felt almost unsettling.

Sigh.

I took a deep breath.

Despite the cozy atmosphere, I reminded myself that I was still in the jaws of a murderous Object.

An Object that takes an interest in humans? According to reports, most of them are killers.

An Object that hands out invitations to humans? Of course, it’s a killer.

Suddenly, the door to the room opened, and a mannequin with the same unpleasant face as the doll I’d seen in the isolation room entered and bowed politely.

"The current guest is a woman with some impressive tattoos. Welcome to Smile Theme Park!"

The mannequin, despite its friendly demeanor, seemed even more dangerous.

"Hmm, a quiet guest, I see. Before you enjoy the park, please take this."

The mannequin handed me a piece of paper designed for collecting stamps.

"What’s this? Is it necessary?"

"Well, I wouldn’t say it’s strictly necessary, but you’ll need it if you want to leave the park."

According to the mannequin, collecting all nine stamps was the key to escaping.

"Then, hurry up and take me to the 'fun rides' where I can get those stamps."

There was no need to waste time.

Whether I live or die, I always face things head-on.

"Hmm, I’m afraid I can’t do that just yet. You see, this room itself is one of those 'fun rides' where you can collect a stamp, so for now, you can’t leave."

The mannequin pointed to a piece of paper on the wall labeled "Room Rules."

Smile Theme Park Room Rules.

…

Now, delete one line from the following rules:

Of the seven colors of food, at least six are poisoned.

The red, orange, and yellow foods are all poisoned.

The red, yellow, and blue foods are all poisoned.

The orange, blue, and violet foods are all poisoned.

The green, blue, and indigo foods are all poisoned.

The orange, green, and indigo foods are all poisoned.

This isn’t really a quiz; it’s more of a nonsensical riddle.

Of course, it wouldn’t seem like a joke if your life depended on it.

Luckily, there doesn’t seem to be a time limit.

I just need to take my time and figure this out.

After some careful thought, I came to a conclusion.

The answer is violet.

All the other colors appear at least twice, so I can cross them out.

The only thing that bothers me is that there’s no guarantee that "violet is safe from poison!"

"Hey, mannequin. Can I ask a question?"

"Of course. We’re here to answer your questions and guide you through the theme park."

I waved the piece of paper with the rules written on it.

"This doesn’t actually confirm that violet is safe from poison, does it?"

"Hmm, we’re forbidden from giving direct help. However, consider this a hint."

Then, in a voice reminiscent of a commercial jingle, the mannequin said,

"At fun Smile Theme Park, there are no attractions with a guaranteed 100% death rate!"

So that’s how it is.

Does that mean I should take out the violet food and eat it?

I opened the pantry and pulled out something with a violet tag.

A simple energy bar with a violet tag.

As I peeled it open and prepared to eat it, the mannequin’s gaze bothered me.

It was staring at me quite intensely.

Why is it watching me like that? Is something wrong?

"Hey, once I’ve solved this puzzle, I just eat the corresponding food, right?"

"Hmm, well, it’s important to note that these are rules, not puzzles. Everything written here is true."

"What?"

Everything written is true?

So, are you saying that violet might still be poisoned?

I threw the energy bar aside and reread the rules carefully.

Right, I need to delete something.

Looking around, I spotted an eraser labeled "DELETE."

"What kind of idiotic nonsense is this…?"

I used the eraser to delete the line that said The orange, blue, and violet foods are all poisoned.

Once I did, the line Now, delete one line from the following rules disappeared as well.

I retrieved a different energy bar from the pantry and took a bite.

There was no poison.

"Congratulations, you’ve cleared your first attraction. Did you have fun?"

I responded to the clapping mannequin with a middle finger.

"Hmm, you don’t seem too satisfied. Would you like me to introduce you to another attraction? There’s one with rules quite similar to this room!"

"No way. I’m not touching anything you recommend."

Following the mannequin’s lead, I opened the door to the room, and my view was immediately filled with large fireworks lighting up the dark night sky.

"Welcome once again to 'Smile Theme Park,' where the festival never ends, 365 days a year!"

Fireworks exploded nonstop against the empty night sky, and a deserted ticket booth stood in the distance.

It was just me and the mannequin standing there in the eerie atmosphere, perfectly befitting an Object.

Wow, I thought I was going to lose my head there.

Step, step.

I walked slowly away from the ride labeled Smile Drop Tower, rubbing my neck.

There were no visible injuries, but I hadn’t been this startled in a long time.

As this was still a theme park, there was, of course, a "drop tower ride," my favorite kind of attraction.

Excitedly, I rushed over and checked it out, and to my surprise, this drop tower had no height restrictions.

Naturally, I eagerly took a seat, lowered the safety bar, and got ready for the ride!

But to my dismay, this was not a drop tower ride, but a drop tower-style gallows.

As we reached the highest point, a noose appeared and wrapped around my neck—a brutal attraction.

The safety bar pinned my shoulders down while a metal wire tightened the noose around my neck.

Instead of snapping your neck, this ride was designed to rip it off—a new concept in executions!

Judging by the setup, it seemed that unless you managed to find a safe seat where the noose didn’t appear, you were guaranteed a hanging.

There was a quiz to determine the safe seats, but the quiz was confusing, so I ignored it and ended up in this mess.

If I weren’t an Object, I’d be dead right now.

Still, I’ve got two stamps already!

I looked up at the sky, drawn by the loud noise.

The fireworks were still bursting non-stop in the night sky.

When I turned around, the mannequin seemed to be in a rather good mood.

It had been following me ever since I left the room, and it seemed to be pleased that I was collecting stamps.

Is it good for them if I collect a lot of stamps?

"You really are something special, sir. Honestly, as a concierge, I sometimes wonder if you were given the invitation by mistake. Why was it given to you?"

Well, why indeed?

Maybe it was a mistake by the doll that tried to give it to me in the first place.

It could just be a slip-up by the doll.

Rubbing my neck, I thought about where to go next.

Even though I wasn’t really hurt, I figured I might as well go get something delicious to lift my spirits!

I looked up at the large map installed throughout the park and found a suitable place.

It was a large dining area named "Food Court."
