I wrote a book once.It was an unhinged fantasy born from my high-school brain, driven by loneliness and too many hormones.It was a world of beastmen, wild freedom, and the kind of romantic attention I could never get in real life. I poured every impossible desire into it: adventure, danger, and yes… a 'lot' of handsome partners.Before I knew it, I had a thousand chapters of pure escapism and pure thrill.Then on a college camping trip, I fell off a cliff.I expected to wake up in a hospital room but nope. I woke up on a soft field of grass, with air too fresh to belong anywhere on Earth.And then something moved behind me.Sticking out of my tailbone was... A tail.My tail?Yellow and black stripes and very, very real.I touched it. Completely real.My ears? Also gone—well, moved. They were now perched on top of my head like a confused jungle cat. And the outfit? Quite revealing, made of animal hide which matched my tail.What was going on?At first, I thought it was a prank. Or a dream. Or maybe karma is finally cashing in. But the more foreign memories evaded my mind, the clearer my situation became.This wasn't cosplay and it wasn't Earth, either.And—surprise—it wasn't even the world from my own book. Welp.I had been transported into a completely different Beastman world as a beast girl called Arinya.Sounds fun, right?Well… it would be, if I weren't apparently the ugliest duckling in the entire freaking savannah! Rejected by every potential mate I stumbled across and sneered at like a freaking eyesore.This was not how I planned my fantasy to come to reality.Trust me—if this is my fantasy come true, then someone needs to fire the author.But then again, after entering this world, I'm suddenly... Attractive.I mean, there's no change to my face and the freckles are still there, but for some reason, handsome beastmen begin to flock around me, because I smell... Pleasant.What's that all about?
