My peaceful school life… is officially over.

Izumiya Ryouta, an introverted otaku, suddenly finds himself surrounded by the top three beauties of the class after a seat change.

In front of him sits the little-sister-type Miyama Airi. To his left, the cool and detached gyaru, Ichinose Yuria. And to his right, the refined, black-haired class rep, Kuroki Ruri.

On the surface, they’re flawless beauties—but Ryouta stumbles upon secrets that none of them can ever let out…

"P-Please…! Just don’t tell anyone about this!"
"From now on, we’re in that kind of relationship."
"This is a secret… just between you and me, Ryouta-kun."

All he wanted was a quiet otaku life—so how did things end up like this?!

Caught between three troublesome girls, an introverted otaku desperately fights to avoid any more chaos in this love-comedy showdown!
