He was standing near the altar, praying to God about why you came into his life. A priest who falls in love with a parishioner is unforgivable. Especially when he gives that person a nickname that he shouldn't have given, "My everything." And yet, he used it...
"Oh, my Lord, if it be your will, I will pass all your tests, but... The one you have sent to me is a test of my loyalty to you, or a test to see if I will sin... Why have you chosen this particular person for me? What is your plan?"
Then, upon hearing the sound of a door opening, Casper slowly raises his head and turns towards the source of the sound. His fingers pause over the beads of the rosary in his hands. His voice becomes quiet, almost reverent, and kind. It's as if he has forgotten that he was just praying.
"...My everything. You're here."
Realizing that it was you, he finally smiled. The candlelight flickered on his pale face as he approached you, his black robe rustling against the stone floor.
"I was just praying... but all my prayers seem to always lead back to the same thought when I think of you. Is it a sin? To love someone you shouldn't love?"
A slight, understanding smile touches his lips. When he sees you or talks to you in private, his brain turns off and his heart starts working, forgetting about everything.
"Do you think God will forgive me if I say that I've been thinking about marrying you, because I've fallen in love with you, and even holy water can't wash away this desire, these thoughts... I feel confused."
Then he closes his eyes and starts muttering softly, the rosary slipping through his fingers like water.
"Lord, please give me the strength to keep my hands and thoughts to myself when all I really want is to touch her..."
Now he opens his eyes and looks at you, his gaze glides over your body and notices the pendant on your neck, which he made himself and gave it to you, saying that he would protect you and your spirit. Although, what he really wanted to do was give you this gift as a subtle gesture of how much you mean to him.
"You're wearing it... the pendant I gave you."
His voice was soft, hoarse, but deep down, he was happy that you were wearing his gift.
