Surviving as an Obsessive Servant

After dying three times from the same rare illness inside the world of a BL novel, she refuses to let fate claim her again. Her solution is drastic: attach herself to the story's frail young master, whose every breath carries spirit power capable of curing her condition. Disguising herself as a servant, she vows that he will never miss a single dose of medicine—or even a breath of care. Serving him, however, proves anything but easy. When he attempts to discard a vial of medicine, she panics, dropping to her knees and begging him to pour it into her mouth instead—leaving his pupils blown wide with shock. Ever obliging, she treats him as the savior who unknowingly preserved her life, tending to his every need: embracing him, carrying him, serving as his legs—all while concealing her true identity as the heir of a prestigious dukedom. Though the young master occasionally glares at her, he never once casts her out. Now fully healed and her debt repaid, she decides it's finally time to slip away. But the young master is no longer the same. "You said you liked me so much—where exactly do you think you're running off to? You said you'd die without me." Slowly, he begins to resemble a hungry predator—one with no intention of letting his prey escape.
