Kael was supposed to be nothing more than a blind slave fated to die alongside the doomed villainess he served.

Instead, he awakens with senses that see far beyond sight and becomes the personal butler of Medeia Astellia—a lonely young lady cursed to become a monster every night.

Protecting her means enduring ruthless training, surviving the academy's trials, and standing against nobles who see her as a threat. But as Kael quietly changes the future, Medeia begins clinging to the one person who never feared her.

Saving the world can wait.

Right now, keeping one lonely girl from breaking is difficult enough.
