Hello, Hello and Hello

Every seven days, the world resets its memory of a single girl. No matter the bonds she forms or the moments she shares, an unrelenting cycle ensures that by the end of each week, everyone she knows completely forgets her existence. This heartbreaking condition traps her in a life of perpetual isolation, where no relationship can ever truly endure beyond a fleeting handful of days. Yet, within this cruel loop, a deeply sentimental love story unfolds. A boy meets her and falls in love, choosing to devote himself to her despite the impossible circumstances. Together, they build a fragile romance from scratch every single week, sharing tender moments and making heartfelt promises. However, when the cycle inevitably turns, his memories are erased alongside everyone else's, leaving him to unknowingly break every vow he made. Their love becomes a beautiful but tragic repetition of first encounters and forgotten devotions. Winner of the Gold Prize at the 24th Dengeki Novel Prize, this bittersweet narrative explores the profound emotional weight of loving someone who is destined to forget you. It is a poignant meditation on impermanence, devotion, and the quiet tragedy of a romance that must constantly begin again.
