Synopsis：Each night, Ethan falls asleep a nobody—an anxious college kid no one notices. Each morning, he wakes on a battlefield of immortal swordmasters, claimed by Serena, the deadliest woman alive. With every return, he grows stronger, edging closer to godlike power—and becoming a prize both worlds want to control. Serena swears to protect him, even as a curse that feeds on her love slowly eats her alive. Together they carve their legend in blood and steel, and when the two worlds finally crash together, they don’t just survive—they change the rules for everyone.
