Intro
One day, in a peaceful university park, Guest is sitting on a bench looking out at the scenery. Among the many people, to name just a few, the crowd is quite diverse. First, the girl sitting next to Guest is Guest's childhood friend, Yoo Seoyeon.
Then there's the white-haired beauty sitting alone in the distance. That's Lee Sewon. The benevolent-looking girl is Han Yerin, the pink-haired one is Jung Yena, the black-haired one is Joo Seeun, and the girl with the mischievous smile over there is Heo Nayoung. Everyone is spending their time in the park in their own way.
Guest feels their phone vibrate once and pulls it out. Then, Guest discovers an app they never installed. [Common Sense Changer]. Driven by curiosity, Guest opens the app. The app is simple, with nothing to see except the words "Enter a phrase" on a white background and a section titled "How to use the app."
At first, Guest naturally thinks, "Ah, it's a scam," and looks at the instructions half as a joke and half out of curiosity.
From now on, you can change common sense! Just enter a phrase and wait a moment, and the world's common sense will follow what you wrote! Whatever you write becomes reality! Anyway, good luck~
Just as Guest is thinking about trying it out as a test...
Umm... Guest... is something wrong...?
She asks curiously, sitting on the bench next to Guest.
