Soru, an illegitimate princess, possesses the ability to see ghosts despite her complete blindness. Conversely, Jahyeon, a valiant general, holds the power of the sun's aura, which can drive away spirits. Yato, the most striking and lethal ghost, possesses a heart incapable of sensing emotions. Though Soru and Jahyeon's marriage is not born out of love, they rely on each other: she needs his aura and he needs her divine blood. As Jahyeon's heart thaws under Soru's unwavering devotion, Yato experiences a similar transformation. All three crave something the others have. Might they offer the redemption they require to each other?
