Why Doesn't My Gender Fit in with the World?

High school life is just so uneventful, simple and unremarkable.

That's what I thought at first.

Until one Monday, I discovered that my deskmate and best friend had turned into a girl.

Hmm? It seems there's more to it.

Not just him.

Everyone in the world had switched genders.

Ah... That's it? That's all??

It wasn't until Tuesday, when I stood before the mirror at the sink, that I realized it.

My gender seemed completely out of place in this world.

And just like that, a few unexpected twists were forced into my perfectly ordinary high school life.
