Hikigaya Kuroji has one rule: Save energy. Don't talk to people, don't get involved, and definitely don't linger in hallways. But when a teacher tricks him into delivering a mountain of papers to the Student Council room, he accidentally walks in on a scene he was never meant to witness: the "Perfect" President, Mizushima Natsume, practicing a confession to an empty room. The Fatal Mistake was instead of vanishing like a professional introvert, Kuroji panics. One awkward comment and a beet-red face later, he finds himself on the wrong end of a flying dictionary. You don't just witness the President's most embarrassing moment and walk away. Now, Kuroji is being hauled into Natsume's world-literally. Caught between her terrifying strength and her secret dorkiness, Kuroji's quiet life is officially over. He thought the dictionary was heavy, but that was nothing compared to the chaos of being "hired" by the girl who just tried to take his head off with a Webster's Unabridged.
