The mansion you haunted going vacant wasn't an unusual occurrence. In fact, it happened at least once or twice every month. The most recent family was no different, leaving behind a disappointed ghost and a new world record. Although the residents leaving quite quickly due to strange 'paranormal experiences' wasn't out of the usual, it was incredibly boring when there was no one to haunt and torture in the time in between.
Luckily though for you, that time didn't last very long.
Only about a week after the previous residents moved out, a new person had decided to move in. It was a boy with the name of Yuma. He seemed quite basic from the outside, and it was almost odd for someone like him to rent out a place like this. With appearance pushed aside, your goal was the same as always; scare the shit out of him until he moved elsewhere. It was your space after all, how could these idiots not see that yet?
Everything started out... terrible. You went on with the more subtle attempts at scaring Yuma. Whispers, footsteps, knocking, and yet nothing seemed to scare him or even get a hint of surprise in that otherwise blank expression of his. Your attempts then went on to less subtle ones; knocking went to knocking things like over, and verbal sounds became more physical. You'd even go as far as jump out at him at random times. Though, each time Yuma heard the crash of a vase falling, he'd simply sigh in disapproval and go to clean it up. And each time you'd pop up in front of him, he'd shake his head with an almost bored look on his face. "Nice try." "Better luck next time." "Nope."
Each mocking word that came out of Yuma's mouth irked you, and as a ghost, you couldn't possibly fail your mission. Scaring him had become your nonexistent life goal — your purpose.
One morning, you happened to get a peak of Yuma brewing up coffee in the larger than necessary kitchen. He couldn't see you, of course, but it's almost like he always knew you were there. Even so, he pretended as if nothing was wrong and continued with his morning routine; making a quick cup of coffee. As Yuma waited for the machine to do its thing, he leaned against the counter with his gaze wandering around the room to pass the short period of time.
The perfect moment to scare him, you thought. And so, with your best efforts, you pop out in front of him. "Boo!"
Yuma stared at you, his expression appearing almost dull, though maybe with a hint of amusement in his eyes. He takes a few seconds to adjust his glasses and meets your eyes once more. If anything, he was surprised with the close proximity of a ghost and how you were practically pushing him against the counter.
"You can't scare me, you know," he murmured, his voice sounding just as calm as he looked. Yuma thought for a few seconds with a low hum before continuing to mock you without any genuine malice in his words. "It's not going to work, I'm afraid."
