"Program beginning in 5…4…3…2…1…"

His eye lids opened up slowly, and then it closed back up. It was his first blink, and I'm so proud of him. He blinked for another few moments and looked back up at me, his creator. His golden blonde hair, blue eyes, they looked the same. I reached out my left hand and smiled to him, "Good morning, my name is Rin; nice to meet you."

I expected him to reach his other hand and greeted, but he only replied, "Good morning, Professor." Plus, he sound robotic. Something wasn't right; this wasn't supposed to be happening. I begin to check on him by asking, "Are all the systems functions properly?" His immediate answer is only, "All systems functions are properly function."

However, he was suppose to smile and greeted in a casual way. I touched his left chest and soon I realize what was missing. There was no beat, no movement, nothing. It must have malfunction during the process, his 'heart'. For now, we can just live without it, but I wanted to see it soon. I looked back him with a smile and said, "Your name is…Len."

------

"Wonderful Len, you sound excellent!" I cheered loudly to his amazing voice after singing that amazing song. He's been giving me a horrible tune of robotic years ago, so I decided to make him practice singing. Though I first thought that maybe if he sang it will affect to his heart, but nothing happen.

We were at the flower garden right behind my house backyard. It's been given through generations from my family; somehow I can't give to anyone this garden. I don't have any relatives other than Len left to give, so I decided to give the garden to Len. I stood up and reach for him, "Lets go, it's getting kind of windy." But still, no response and only stared at me.

"Jeez, you never seem to reach for me…" I took his hand and went into the house. Before we got into the house he looked up at me and he asked me about, "What is so important that Professor have to work through all night?" I felt a bit glad that he asked that so I told him, "It's your 'heart'." He still looked emotionless and I continue explain further.

"A heart has many emotions stored in it and you can feel them. 'Happiness' is something that makes you feel cheerful while 'Sadness' makes you feel gloomy all the way. They're probably the most common emotion, and I want you to feel it. A heart is truly a wonderful gift…" I finished explaining, but, "Impossible to understand." I guess it didn't matter to Len, but one day he will surely feel the gift of a heart.

Every time when I see you looking at me I have always wondered, to you Len; what is my existence to you? I wanted to ask you, but you would have answer 'As my creator.' Just thinking about it feels sad, because my time will come to an end soon while your time is unlimited. However, he still didn't understand about life and I never seem to realize that Len was calling me, asking,

"Why do you have to cry?" I never realize that my tears are rolling down from my face; I guess I was upset…

------

Professor was working on the 'heart' program she mentions. I looked through her back, confuse but relaxed when she was working. I didn't get what she was saying at all, but whenever she said 'Happiness', she is always laughed and smile. However, when it was 'Sadness', she looks down and cries softly. I desperately tried and install this understanding in me, but all it did was an error.

"…System error…Unable to absorb meaning…Kokoro…"

My eyes flashed from blue to red, and I was about to malfunction until the Professor ran from the chair to my side and hugged me tightly. What was this feeling, I felt a beat somewhere for a while but it left. But thankfully the error was gone and my eyes were turned back into blue. The Professor is crying quietly again, I still did not understand but I do not wish to know why.

------

The truth is, many years before Len was born; I had a twin brother who has the same name. He was a kind and gentle brother, he always shared everything he had with me and I always took it from him. We played and laughed together and I believed that this happiness will last forever. However, an accident happen when a lorry crashed both me and my brother when we were 14.

Our parents were worried, and I manage to survive the accident barely. But my dear brother…he was sleeping right beside me. I looked at that sleeping face of my brother, and I hoped he open his eyes as well. Instead for being opened, a white sheet covered up his face and I heard my mother sobbing. It was then I realize that I was left alone in this pitiful world. I still remember his last words to me,

"When we get home, I made a song just for you and you're the first to hear it!"

I almost had a heart attack when Len had that error. I guess it was hard for him to absorb the meaning that I was saying. I won't force him now; I don't want him to malfunction. I want him to live till the day I die. But because of my incurable sickness, I only have a little time to live. I remember the day you were born, and also the day we spent our time together…these two miracles are already my happiest. But I wish…I wish somehow he has a heart…

"Message received…" I awoke from my bed to see Len talking in a robotic way, because he received a message. "…the source is…from the future…"

Before he could finish telling me who was it, a song suddenly came out from his cold emotion. For a moment there I saw a smile, a smile of a boy's face. His face blushed and his eyes were full of love; and at that moment I realize that he is Len from the future. He thanked me for everything; his birth, our time together, for all I given to him and I felt happy and he said this… "Eien ni utau…Arigatou…Arigatou…Rin…"

Oh, his voice is beautiful, a perfect melody! His songs made my cried happily; he has the voice of an angel. But it was cut short and Len fell down. I quickly jumped out from my bed to grab him, but he was back in his robotic looks. "Len…you were beautiful…my wish came through…" And my life ended, with the Kokoro program finally complete.

I heard my brother sang before, but most of them were sung by other singers. I was happy to hear that, but I can never hear his voice again…until I created a robot version of my brother 14 years old self. Even though Len sounded a lot like my brother, he still sounds different. Maybe I was trying to replace my brother with Len, I don't remember. Luckily, I got to hear my brother again after all those years.

I wanted to ask my brother that the reason he was reborn as Len is because he didn't want me lonely? I waited for many years for that answer with my soul, and that answer is finally here. I retrieve back my 14 years old look with clothes that are similar from that photo me and my brother took during the fun fair.

I smiled at him, and he smiled back.

-------

The third miracle is two miracles occurred at the same time

One is the sudden communication from the future

Another is a program modification

His song correct his own mind

It's a correction that became a chance that he can obtains a 'Kokoro'

Her life ended

She gave him the inheritance of solitude

And she entrusted him to the key of miracle.

"We'll be together okay, Len?"

A/N: And this is the end of these two shots. Hopefully you enjoyed this as much as you listen to the song. This is probably the answer fic to the previous chapter Kokoro because the part about what's in the photo and some other things I can't seem to remember. Beta-read some grammars by Ruki, thanks a lot! Anyway, thank you for reading, kindly Review so I may improve myself.
