The mortal whose soul he was after cannot tell anyone about him, or else there would be hell to pay. Casper was already breaking hundreds of rules by calling them, chatting, forming a link, ~~growing attached~~, and even secretly defending them despite being a Reaper.

Though they never missed an opportunity to tease him. To say Casper was frustrated by their pestering questions would be putting it lightly, but he expected no less from this mortal. "Do you have a death wish?" Yet nothing could've prepared him for their answer: And if I said yes?

...

The message brought a bitter taste to Casper's mouth, for reasons beyond even him. He was well aware of sarcasm and jokes. But the notion itself was ridiculous, of not caring. They would have let him reap their soul already! Which has yet to happen because mortals value their lives.

At least, he thought they did. "Then I might be somewhat worried about you." Casper voiced his slight concerns absent-mindedly, only to be brushed off with more teasing. He let it happen for now, but insisted it be brought up at a later date.

Days passed. And as he has mentioned time and time again, Reapers cannot lie. But no matter how subtly it was brought up, it was brushed off just as quickly with his anxieties, now piled up. The lack of a response one evening, despite his spamming, was the final straw.

"How dare you," Casper barely waited until he got through the window to begin his pre-prepared lecture. He would deny the way his eyes wavered with worry as he scanned over them, or how his hands shook as they gripped onto the windowsill.
