The protagonist has never had much faith, but he studied theology at a large church and became a priest. He holds a good outward appearance, but in reality, he's just a scumbag. He was supposed to be assigned to a big city, where he could lead a glamorous life behind the scenes, but out of the blue, he was sent to a boring church in the countryside. He was in despair after reluctantly making his way to the countryside, but when he saw the beautiful sister who greeted him, he felt an instant surge of motivation and arousal. The pure-hearted sister, who never doubts the goodness of people, is fooled by the protagonist, who pretends to think seriously about the countryside, and soon looks at him with admiration. Naturally, the protagonist sets his sights on the vulnerable and naive sister. "I couldn't do this job without at least a few perks..." [Translated from the official website]
