Trevor Abbot was just a butler.

The head manager of the Veleen household organized the other employees' chores and led the house to disable chaos from entering the large wooden doors.

Now, he swam in a pool filled with odor irritating her nose and Trevor's body visited by flies. The only clue about his death was that note.

K. The letter, crumpled and drowned in a fountain of blood and water, had been signed by someone with an initial of K.

Not much people she met had the letter K as an initial. Not much and she remembered just two of them. Yet this unsettling feeling bothered her to the core. Familiar and at the same time, not so familiar. The mixed feelings reverberated in her heart, creating a sense of nostalgia that filled up her body. Soon enough, the sentiment pulled her heartstrings and gripped on a memory she hid away from the surface.

"You know I'm going to disappear soon, right? Then you can't ever find me."

Those words were the last she heard from him. She didn't even say goodbye. She didn't even call out his name for the last time. Nothing. She had stood stupidly years ago, watching his back growing smaller at every step he took. It was no use nowadays, she wouldn't see him again.

Besides, for all she knew, he was an imaginary friend created by her brain to be relieved of the loneliness she felt back at the academy. How could she bring back the imaginary friend whose appearance she barely could describe anymore? The memories with that friend was blurry though she did remember the name, echoing in her head.

Kei. That was it. She envied him too much. Maybe it was the reason why her throat had felt dryer than it could ever be when she wanted to say so much yet not a single world came out.

Even though Aiya couldn't remember how he looked like from her perspective, the little talks they shared were all in her head and stacked like important files deeo inside her brain. It all was probably in her head, she wasn't too sure since most of it were faint, but she did treasure him as her rival and the person she most wanted to be in order to catch her father's attention.

And even though his face had failed to be recalled by her, she couldn't forget how he made her feel. The heart's the greatest brain, one that wouldn't forget everything so easily as the mind could.

He had the nicest personality; kind, humble, sweet, gracious, and more words Aiya could use to describe him. He had a cheerful home with loving parents that she incredibly desired for. He had friends, loyal and faithful to him. Aiya had seen his smile once and it was bright as the sun when he was around them.

She didn't like it, perhaps due to the fact she hadn't experienced it yet and possibly never will she curve and stretch out her lips that far.

Diamond Veleen was never known by the public even if her father was a famous man. She wasn't invisible, people could see her alright, but all the students in the academy that taught love hadn't shown a single shred of warmth to her. She wasn't lonely at times. She still had her three year old snow white bunny called Oreo. It wasn't the same but she didn't even try to change the circumstances at all.

Rather than the alteration of herself, Aiya created a persona. A profile that the whole community knew of.

Midnight Detective, a girl with astonishing crime solving abilities who only enters the scene at night. A masked girl who had been wronged as a cosplayer for several times. And a loner who longed for the light to shine brightly down at her.

She was both girls but a big difference gap existed between them. Midnight Detective needed Diamond Veleen for the masked person to live.

Beware, they're coming for you DV. Signed K, the letter dictated.

The writer of the piece of paper also knew her initials which meant that he or she knew Aiya's true name. Then again, it might be a different person and she was just an over worrier. But rethinking on who could've known her identity was troublesome and she could not erase that imaginary friend out of her head.

From the starting point, she wondered what was real and what was not. It could be possible that the friend of hers was real and she misremembered it. Either way, whatever the truth was, both weren't a happy choice.

"Who is DV?" Inspector Graham squinted and scratched his chin, absorbed in deep thinking, while Robbie scanned the paper Aiya held tightly with her gloved fingers.

"Hold on!" Aiya placed breaks on their thoughts, trying to analyze another thing. "How come nobody had seen the killer when they were in the center of the plaza?"

The fountain was determined as the middle of the city by the current mayor's ancestors. It wasn't that accurate yet they treated the built water sprinkler as a monument which had the statue of a baby cupid and his bow and heart arrows with small wings.

The water was no more crystal blue. In fact, it turned into bloody red by each second, removing all the transparent background of the liquid. The body scratched with deep small wounds that unobservant eyes wouldn't see and a bash on the head cracked and opened his skull. But the most important fact were the cuts.

Those weren't made by ordinary knives. Those were precise, deeply thrusted to slice through his vital points. Aiya immediately discovered that they were dealing with someone trained and someone who had dealt with such a monstrous experience.

"That's a part we don't know. The murderer must be an expert to do such a crime in front of thousands of citizens," Jules, a policewoman had her name engraved on her name tag, same as Robbie. Only hers was pinned on the right side of her uniform.

"So, nobody had seen him s-stabbed?" Aiya attempted to make the last word stable, disregarding the irk jumping from letter to letter. Trevor just had an unsaid bladed weapon plunged deep to him as she felt shivers sent down to her spine, being reminded of his death.

"Stabbed?!" Raised and curved brows carved Robbie's face.

Jules added to their inquiries, "Didn't his head smack down the tiled boundaries of the fountain?"

Aiya shook her head with firm sturdy lips, avoiding the quivers. She calculated the facts all at once from the scars to the cracked skull. There was no mistake. Those were open wounds, deep ones, cut by a sharped small blade. Yet no weapon was seen. No clue had been seen. Not even the crime was watched by a single person.

The murderer was a sly person and could be anyone, could be anywhere. Even amongst the crowd.

"Even the cleanest room still has some dirt left. The experienced criminal would still leave traces behind, traces he didn't see himself," Inspector Graham reminded Aiya that every case is solvable. It just took time to get it done right.

"It was me!" A voice from the crowd boomed, silencing all the people's whispers.

The crowd evaded him, retreating to the sides as the person was revealed. His platinum blonde hair stuck out as though he just got up from bed. His chocolate eyes were glimmered with intensity and mysteriousness upon the starry night. The black necktie around his neck strapped the collar of his blue formal attire as his belt wrapped around his waist, demanding his dark pants to cover his entire legs, that suggested he just came out of internship.

There were two people that Aiya knew who had the letter K as their name initial. One of them was Kei, a person who she doubted whether he was imaginary or not.

Then there was her half older brother - Karl Quinn Veleen. Their father even gave his last name to him, proving that there was at least a bit of live shown to him; something that Aiya had sought for so long and he achieved it the second he was born.

"Quinn," she muttered with uneasiness devouring her.

That person had killed the man who expressed a bit of warmth that she wanted to hold onto. And when she finally got to embrace that blaze, Quinn stomped on the flame.

But something just wasn't right and Aiya was sure of it. There's something else. Something she had missed. And no matter who that person may be, he still murdered someone who meant much to her.
