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!

Yuuto Hatano has replayed his favorite dating sim, After School Flare Star, more times than he can count. Surely, his real school life would be way more fun if it were more like that game...but after the thought casually enters his mind one night, he wakes up inside Flare Star's world—not as the protagonist Shun Ogasawara, but as the villain, Kanji Aku! With every heroine's affection starting at rock bottom, his dream of romancing them all is already in shambles. Worse yet, one wrong choice means instant death. Armed with his expert game knowledge but hindered by his low stats and the heroines' lower affection scores, Kanji must survive the game's deadly routes to win over the girls and return to the real world!
