Naoki Iijima belonged to the Media Research Association, a group of hardcore otaku which included a pretty girl named Miyu Honda.
To his shock and delight, Miyu revealed a crush on Naoki.

It was his first relationship with a girl.

But Naoki soon learned Miyu wasn't just into him. In fact, Miyu-miyu" was dating everyone, having sex with everyone...
She was a yariman bitch who got wet for any virgin nerd!

When they found out, the group plotted revenge on the two-timing princess.

-------Except for Naoki. He alone was smitten.
His and Miyu's love was pure... he was sure of it... even knowing the filthy truth!

The choice is yours as Naoki...
to pursue the ideal or to face the reality

... When it comes to pure love, a person can do mad things!
