Kyou Kara Tsukaeru Isekai Renai Manual

Haruchika Isezaki’s confession to his childhood crush is interrupted mid-sentence—not by rejection, but by a blinding light and the wrenching sensation of being pulled across worlds. When he regains his bearings, he stands before the goddess Clementine, who wastes no time explaining his predicament. The Demon Lord’s curse has robbed seven young women of their capacity for love, and without their affection, the next generation of heroes will never be born. To break the curse and save the realm, Haruchika must make each of them fall for him—genuinely, completely, and simultaneously. The mission is absurd, but the alternative is unthinkable: returning to his world without ever hearing the answer to his confession. Armed with an encyclopedic knowledge of female psychology, honed through years of obsessive study, Haruchika accepts the goddess’s request and steps into a role no one else could fill. Yet winning hearts is not the same as understanding them, and each girl carries her own wounds and defenses. As he navigates a treacherous landscape of distrust, hidden pain, and the lingering shadow of the Demon Lord’s malice, Haruchika discovers that love is far messier than any theory he ever learned. This is a romantic odyssey where the fate of an entire world hinges on the sincerity of a single boy’s heart.
