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!?
