やり込んだ恋愛ゲームの悪役に転生したので、原作知識でヒロインを攻略します

あらすじ

Yuto 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!
