A Spell to Erase the Devil's Smile

Leo, who embarked on the path of knighthood following his parents' incident and somehow ended up with a strange epithet, suddenly receives a support request from the Imperial Guard—an elite among elites.

What he was asked to do was nothing less than to disguise himself perfectly as a noblewoman. However, his compatibility with his assigned lover is abysmal, and frustration mounts from the forced circumstances. Still, enduring through sheer determination, when the operation finally commences—a series of unexpected incidents guide Leo's fate in an unforeseen direction.
