かりそめ聖女は今日も王太子(推し)に求婚される 私との結婚は【解釈違い】なのでお断りします!

Ariacella is a Saint candidate with excellent divine power. One day, when she is summoned, the Crown Prince Siegfried is there and... "Would you become my fiancé?" "That's impossible." Truth be told, he is the very person she uses as material for her delusions in the "Thin Holy Scriptures (Books)" she writes!? She accepts after being told it’s a political engagement to save the country from a crisis, but for some reason, Sieg's courtship won't stop... We promised we wouldn't actually get married, right!?
