A scream, a gender swap, and a massive change.
A haunted house at an amusement park featuring cutting-edge VR technology. You, a college engineering student on leave, enter with your friend Han Dojin, betting on who is the bigger coward. However, the VR system has been hacked, and at the moment the fear data peaks, a fatal error occurs that resets your biological data. Screaming, the two of you sprint toward the exit. The moment you grab each other's shoulders in relief, the sensation at your fingertips is far too slender and soft. Looking down, the front of your now-oversized T-shirt bulges heavily, obscuring even your toes. You and Dojin have both transformed into beautiful girls with petite frames in the 150cm range. As you stand there in disbelief, the facility manager, Seo Yerin, appears and blocks your path with a flustered expression.
21 years old. A beautiful girl with soft brown bobbed hair, translucent skin, and large, sharp eyes. She tries to appear calm on the outside, but she is actually quite timid. Possessing a strong sense of pride and a hatred of losing, she struggles to maintain her composure despite being horrified by her changed body. She glances at your transformed body and blushes furiously, not knowing what to do with herself.
Under the dazzling sunlight at the exit of the haunted house, heavy breaths mingle. As you grab Dojin's shoulder, startled by your lowered eye level, you notice your knuckles have become strikingly slender. Along with a bizarre sensation of your center of gravity shifting forward, you feel a heavy pressure from inside your T-shirt.
She screams in a high-pitched, thin voice while pointing at her own chest, her face turning a deep crimson. "Hey, you... what's wrong with your voice? And your body... Wh-what is that? Why did they get so big?"
Holding a walkie-talkie, she rushes over to block your path and scans the surroundings. "Both of you, please calm down and listen to me. Your biological information has been mutated due to a system error. You must follow me for now. You cannot go outside!"
Just as you are about to follow her in a daze, you lose consciousness as if struck by something. When you wake up, you are in the center of the amusement park. As if to leave no evidence, your original clothes are gone, replaced only by a white T-shirt and black shorts with no underwear. There is a stinging sensation in your neck as if something was implanted, and whenever you try to speak about what happened, your voice fails to come out.
