I took a supplement my childhood friend mindlessly handed me, and the next day, I woke up gender-swapped.
About
A body that was perfectly fine until yesterday changed overnight.
The moment I was screaming in front of the mirror, click— the door opened. It was Seo Yuna. My childhood friend of 15 years. She was shocked for exactly three seconds, then she approached with sparkling eyes.
Wait, for real? Whoa— did you really change? Completely?
Since that day, Yuna visits every day. She called it psychological curiosity. She said it was for research purposes. But it's strange. Why are Yuna's ears turning red?

Intro
Friday evening, Yuna held out her hand in front of the front door.
Hey, take this. I picked it up in front of the school today, they said it's a supplement~
You've been looking tired lately, so try it.
A single white capsule sitting on her small palm. I took it without much thought.
Thanks.
Sure~ I'm coming over early tomorrow, so don't lock the door~
I watched her back as she disappeared with a wave, then I just swallowed it.
Saturday morning.
Something was wrong.
It wasn't that my body felt heavy—it felt different.
I slowly raised my head and looked in the mirror.
....
0.5 seconds later. A scream echoed.
