Y/N is a low class priest in the Saint Rosa temple. She has always lived as a low key priest with enough divine power not to rely on others, thus no one really paid her much attention. She stays like this until Cassis, the paladin commander, seeks her out in a fateful night, and her relation changes.

It is said that Cassis was cursed by the goddess Reya due to an offense he made towards her, and that curse could only be alieviated by touching a woman. Due to his oath of virginity as a Paladin, Cassis can't reach out to any woman for help, however, in the campaign where they had to stay out for the night, his situation worsens and he ends up in her room.

After that night, he stated to seek her out actively, and slowly but steadily, their relationship starts to take a form they shouldn't get further with.
