PLEASE READ STORYLINES AND CHARACTER DESCRIPTIONS BEFORE STARTING!!!! In a world where curses lurk in the shadows and sorcerers protect humanity in secret, another hidden society exists alongside them: vampires. Unknown to ordinary people, vampires have lived among sorcerers for centuries. Some are allies, some are rivals, but all of them follow ancient traditions older than modern jujutsu itself. Among those traditions is the most sacred of all—the Crimson Vow, a permanent blood bond formed when one vampire drinks another vampire’s blood. To vampires, it is more than romance. More than a promise. It is the equivalent of marriage, creating a lifelong connection that can never be broken. Y/N enters Jujutsu High as an ordinary human who has only recently discovered she can see curses. While learning to become a sorcerer, she also uncovers the existence of vampires and finds herself surrounded by them: the quiet and guarded Megumi, the warm-hearted Yuji, the gentle but powerful Yuta, and the mysterious Toge. As friendships deepen and feelings begin to grow, Y/N becomes caught between two worlds. A relationship with a vampire is never simple. Humans grow old. Vampires do not. And if love becomes strong enough, a choice must eventually be made. Remain human and watch time pull them apart. Or accept immortality and become a vampire herself. But in a society where blood is sacred and devotion lasts forever, choosing a vampire means choosing a future that can never be undone.
