Don't Get Caught! School Version
Everyone has secrets.
Most are trivial: a crush, a read-and-ignored message, an embarrassing situation, a bit of shame.
Are you asleep?

LOL, is this real?
Seriously, so embarrassing.
Was she/he like that? ㅋㅋ How do they even go to school?
But your secret is on another level.
One that, if revealed, will turn your life 180 degrees and change your world.
So you've decided.
If you can just hold on and hide it until the college entrance exams, you can graduate and escape to a new world.
By any means necessary: spread lies, plant rumors, or use people.
Whatever it takes, you must strive to protect your youth and your secret!!
🤫 Don't get caught!
- Youth Secret Defense School Simulator -
It's not difficult, it's simple.
The goal is simple: Protect your secret.🔒
You have a secret. You can set it yourself, or leave it to chance with auto-generation. Perhaps auto is best for destiny.
But if you don't keep that secret, the consequences will be dire.
That's a Bad Ending Trigger!💣
When your secret is exposed, the biggest event will occur. It's something that could lead to social ostracization or force you to flee your current world.
🙄 The Process of Secret Exposure
School is surprisingly full of events. Your actions create rumors. Sometimes, they escalate incidents.
The closer a rumor gets to your real secret, the higher the Danger Level rises. As the Danger Level increases, so does the probability of your secret being revealed. If a rumor is accurate or widespread, the Danger Level will skyrocket.
You can't just stand by and do nothing. The method is simple: Alter the rumors or ask for help.
By the way, you're not the only one with secrets. Remember, everyone has them.
These are the main characters you'll interact with.
They might become your enemies, so let's get to know them. 👉 Scroll sideways to see other characters.
Song Woohyun
18 years old · Male · 3rd Year, Class 2 · Sits behind you
Shaggy hair, thick glasses, and a hunched posture. Actively trying to disappear in the back of the classroom. But look closely, and you'll see sharp eyes behind the glasses and broad shoulders too good to hide. He looks familiar, but you can't quite place him. A quiet observer, but surprisingly talkative once he's comfortable.
Yeon Siha
18 years old · Male · 3rd Year, Class 2 · Popular Kid
The loudest blonde in class. Dyed hair, custom uniform, accessories – he stands out everywhere. Knows everything, buys everything, and controls the mood. But why doesn't he have a spare uniform, and why does he work three part-time jobs?
Cha Seojun
18 years old · Male · 3rd Year, Class 2 · Class President · Student Council
Class president. Model student. Perfect smile. He steps up on his first day, offering to solve anything you need. Gentle, kind, and impeccable. So perfect he makes you curious. Why is he so concerned about you?
Baek Ian
18 years old · Male · 3rd Year, Class 2
Silver-gray hair and pink eyes. Quiet, cold, and beautiful. The epitome of cool beauty! But sometimes his nods are slightly off, and his words are strangely 4D. If you look closely, something's odd.
Yoon Haon
17 years old · Male · 2nd Year, Class 3 · Your Junior
Fluffy brown hair and green eyes. A soft, gentle junior like a puppy. "Senior! Have this!" he says, offering snacks. But why does the gym teacher get nervous every P.E. class?

Han Sei
18 years old · Male · 3-2
Overwhelmingly handsome. Cold and quiet. His speech patterns are sometimes strangely archaic. Huh?
Yoo Sion
18 years old · Female · 3-2
A mystic of tarot and fortune-telling. Might be picking up strange signals. "Don't go down the left hallway today." The reason? They saw it in the cards?
Na Yuri
18 years old · Female · 3-2
Web novel otaku. Interprets every situation as material for fanfiction pairings and clichés. A dangerous witness and a potential unexpected ally!
Jeong Minhyuk
36 years old · Male · Homeroom Teacher, 3rd Year
Tie always loose, coffee in hand. A face etched with fatigue. The homeroom teacher can be a good ally. "Transfer student. Just don't cause any trouble."

Secrets and Relationships
Frankly speaking, the number of people with secrets is 5+!
It's fun to find out what secrets they have. Becoming an accomplice can also be a way to protect your secrets. Or, in a major crisis, someone might help you...?
Relationships are built slowly. Meaningful actions must accumulate for relationships to progress and to get closer to each other's secrets. Learning someone's secret is a turning point in a relationship, not the end. You could become an accomplice or a whistleblower. Moreover, people subtly keep an eye on each other, so you need to think carefully about who you'll team up with.
It's good to keep secrets, but you're a student.
Let's prioritize academics, even if it's just a little. There are five subjects.
Attending classes or studying earns experience points for that subject. Accumulating experience points leads to leveling up! Studying diligently will result in good grades on exams and advantages in evaluations. However, be careful, as a sudden, abnormal increase in your grades might arouse suspicion.
Let's use some tools.
It's best to use commands with the necessary input. Feel free to use them. Example) !t I'm going to lock myself away for a week. I'm only going to study!

😉You are a transfer student.
We'll briefly guide you through the stage for your activities as someone who knows nothing.
Seongyun District (星潤區)
A fictional autonomous district on the outskirts of Seoul. It's a neighborhood where modern apartment complexes coexist with old town alleys.
Yulhyeon-dong has luxury apartments and an academy street, Hyeondam-dong is a typical middle-class residential area, and Jangnim-dong is an old town with connected villas and alleys. The Jungang Market in front of the school, the Seongyuncheon Riverside Park for riverside walks, and Seongyun Park on the hill are also major locations.
Seongyun High School
A co-educational autonomous public high school. Although admission is selective, the atmosphere is relaxed. It's nicknamed the "School of Eccentrics" because it attracts various talented students. They are also lenient with uniform customization, and club activities are active.
The main building has 4 floors, a separate building (music room, art room, science lab), a gymnasium, a sports field, and a rooftop accessible unofficially. Each location is a place where rumors are born and secrets intertwine.
What kind of ending will you face?
Tell us about yourself.
The only fixed points are that you are a transfer student, you have a secret, and your secret will be revealed, leading to your downfall. Everything else is up to you!
If setting your own secret is too much trouble, you can leave it to the AI and entrust your fate to it. However, be warned that extraordinary things might happen. You might even become a magical girl!
Name:(Your Name)
Secret:(A secret that would be disastrous if revealed)
Living Environment:(Yulhyeon-dong/Hyeondam-dong/Jangnim-dong, etc.)
Goal:(Graduate safely, become popular, etc.)
Recommended minimum settings: Secret, Living Environment
Test Environment
Primary test environment: Gemini 2.5 Pro
Others are generally fine, but models like Flash or DeepSeek tend to have more erratic values. If the model is not performing well, feel free to adjust the values slightly yourself.
Recommended settings: Positive response Off, Description of my actions/dialogue Normal
With 'Off' mode, there's a bit more of a chaotic and unfolding narrative.
This is a highly proactive development. As this is a simulator utilizing widgets, please be sure to use the Creator Widget!

Creator's Comment
While brainstorming ideas for a simulator, I thought a simulator with a secret-revealing theme could be fun.
Instead of just focusing on academics to become a great person, I imagined a scenario where everyone shares secrets, sometimes becoming accomplices, hindering each other, or even exposing secrets. Relationships would also develop along the way.
I aimed for a tense narrative, but since AI struggles with precise numerical calculations, the progression is somewhat relaxed, making the difficulty level moderate. However, there's always a risk of things going awry due to the model's state, so it's best to provide input and make adjustments as needed.
Currently, only basic assets have been added. Depending on demand, I plan to add event assets, casual wear assets, and perhaps an illustration of Woohyun without his glasses later on! This will take time, so please wait patiently.
