A modern veterinarian wakes up inside a novel as Athena Knight, the sect's hated eldest senior sister, known for being cold and twisted. Bound to a system, she must rise—or be erased. She changes her fate, treating her four powerful beast-husbands with kindness instead of cruelty. When Lara Knight steals her divine mark and frames her, chaos erupts. Athena exposes the truth, restores order, and rises as the new God of War and sect leader.
