I'm Ueda Shinji, a first-year high school student.

It was my first Christmas Eve with my girlfriend.

But on the day itself, she stood me up for our date and then unilaterally broke up with me.

"Sorry, but otaku are gross, so it's not going to work."

Appearing before me, heartbroken after being dumped, was Matsumoto Rika, the gyaru from my class.

Rika listened to me as I talked about my pain, and she encouraged me.

"You, become my boyfriend."

Suddenly, she confessed her feelings to me.

Her true intention was... revenge against my ex-girlfriend.

Actually, my ex-girlfriend had been secretly cheating on me with another boy in our class.

"You and I will date. Then, we'll keep up this fake relationship. We'll act super lovey-dovey in front of your ex."

I teamed up with Rika, and we entered into a fake-love relationship to make my ex-girlfriend regret what she did.

At first, it was a relationship solely for revenge, but gradually, I found myself drawn to Rika’s inner qualities…

And Rika, from a gyaru, gradually transformed into a refined beauty.

Meanwhile, my ex-girlfriend realized something after breaking up with me.

The guy she actually started dating was quite a scumbag, and that I was actually the better choice.

But by the time she realized, it was already too late.

I had already become Rika’s real boyfriend, and there was absolutely no room left for my ex-girlfriend to come back into my life.
