A beautiful music expressing a sorrowful voice but at the same time soothing to the soul, echoed inside the quiet room. It was almost dawn and just as the song pierces through one's soul, the moonlight was also piercing through the glass windows.

Sei that moment, who was immediately halted and went frozen upon hearing the sound looked as though a thunder bolt just struck him. It was because that piece was the last song his mother played for him years ago. Causing him to slowly clenched his fist tight before he violently covered his ears with his palms.

He doesn't want to hear that song, but no matter what he does, the sound still pierces through him. The soft gentle song was like a voice of an angel desperately trying to reach his seemingly irredeemable soul. Making Sei to eventually bend his body as he bumped his head on the table. His hands were still covering his ears but the longer he struggles not to hear it, the sound just seemed to be getting louder. Slowly piercing through the almost impenetrable darkness within him.

Until a minute went by and the song didn't stop. As though the person playing it was telling him that the song will never stop unless he gives in.

"Zaki, make it stop." He then ordered with his horrifying tone. However, the boy behind him didn't make a single move as though he didn't hear a thing. Leaving Sei without any choice but finally gives in.

His hands which were covering his ears then slowly fell. And the moment he finally heard the song clear enough, he stood with his fist clenched so tight.

He began to move his feet and slowly followed the source of the sound. While Zaki just followed him as though he was literally his shadow.

As they walked, the sorrowful sound just kept piercing through him even deeper. Until finally, they stopped just in front of the school's music room. The door was widely opened and the moment Sei saw the person playing the piano he just froze again in place.

A girl seemingly two or three years younger than him, wearing a white patient dress was sitting on the piano stool, playing incessantly as though she looks as though she was a glowing. An existence that seemed to be out of place from this world enveloped with darkness.

Sei could only see the side of her face and the moment he saw her crying quietly, for unknown reason,something just seemed to strike his hearth. The moonlight streaming across her face made her tears appeared as though they were endless falling crystals.

That moment, the picture of the girl quietly crying in front of him and the sorrowful song she's playing made his dead heart seemed to revived again. And the next second, tears just began to quietly fall from his eyes as he kept staring at the girl while the sound just kept ripping through the deepest abyss within him.

Until Sei slowly fell into his knees and he just began tugging his own hair.

He began to cry. The tears that never fell from his eyes for many years seemed to just flowed and he couldn't stop it anymore. He hugged himself as he continued crying quietly. His own nails pierced through his flesh and blood dripped on the floor.

And for another long while, the sound of the piano didn't stop. The girl playing the piano was still crying just like him as if both their hearts were both ripping apart. As if she was crying for him as well. It was as though she was playing for him to tell him to just cry it all out until nothing is left anymore.

The tears of the girl, the cry of the piano everything made his heart at the verge of burstinh. The sound was like the song of an angel pulling him out to the deepest abyss of hell.

And as time goes by, the song filled with agony and sorrow started comforting him as if someone was now gently caressing his head. As if someone was telling him to raise his head again. And strangely, the song started soothing his heart while a little glint of hope re-appeared across his eyes. Causing Sei to raise his head once more.

He clenched his fist and he stood as the song was reaching its end. He ran back to the computer room while the piano was still playing.

And the moment Sei reached the computer, he immediately cancelled the preparations he just created. He began to destroy every existing traces of the unforgivable crime he was about to do minutes ago.

And the moment he finally set the computer to delete everything on its own, the sound of the piano stopped. Causing Sei to turn towards the door and he was about to move out the computer room when they heard voices. Two guards of the building came along with a woman that appeared to be a nurse and they took the girl away.

Seeing Sei just froze in place as he just watches the girl's back, Zaki immediately spoke.

"Do you want to go see her?" he asked and Sei looked at him for a while before he shook his head.

"People will soon come here to investigate we can't involve her." Sei replied with his weak voice before he just suddenly moved weakly and hugged Zaki.

Zaki was surprised but before he could react, Sei fainted. Causing Zaki to just sigh with great relief before he slowly put Sei in his back to leave the place.

However, as they were about to leave, Zaki decided to sneak first in the clinic to see the girl's face. But before he could, a woman came out of the room taking the girl with her, causing Zaki to just hide again.

Gladly, he finally saw her face. And that moment, Zaki, who have such an almost super human memory carved the girl's face in his head.
