Fifteen years ago, a demon and his minions reduced an ordinary town to rubble. Piles of corpses formed mountains, and wild fires burned for three whole days and nights. The town transformed into a grim and desolate ruin. Amidst a thousand graves, it seemed to hide something else—a buried truth, lost memories, and a reset time. Fifteen years later, the surviving girl has grown up once again, yet remains unaware of everything she had experienced—unbreakable bonds, forbidden love, and all the destined sacrifices and encounters. The beast tamer who couldn't tame beasts finally encounters a beast that resonates with her heart. However, this beast seems to exist beyond any Beast Encyclopedia. Where does it come from? And who is he? Can she remember everything once more? If those memories are lost, can their reunion still be called a reunion? "As long as I can stay by her side, it doesn't matter what identity I assume." Is a forgotten vow worth sacrificing one's life for? "She doesn't need to remember; as long as I remember, it is enough." *** Note: The original text of this novel is non-English.
