Second year of high school.

I had a boyfriend I loved and a best friend I trusted more than anyone in the world.

I thought this happiness would last forever.

But that was all just my own delusion.

One day, I saw the two of them walking together, holding hands.

"Sorry. I've decided to date Mio."

With those words, my world crumbled.

It didn't end there.

My best friend took away my place in school and spread lies everywhere.

Before I knew it, no one believed me anymore.

Laughed at, whispered about, I was completely alone.

The day I thought it was all over...

"Are you just gonna end it by crying?"

The one who spoke to me was a boy known as the school's biggest troublemaker.

"If it was stolen from you, take it back."

"If you want revenge, I'll help you."

From that day on, my revenge begins.
