PROLOGUE

I was destined to die. I know that. But I want to leave something behind... Something that reminded everyone of me... Proof…that I existed in this world... A Proof of My Life...

Chapter 1: Bonds from a Storm

I will soon wither. My eyesight will darken. I will be blind, deaf, and...

Lifeless.

My voice, that I used to sing with Len, the most important person to me in the world, will soon wither too.

I wish I could sing one more time… Just one more time with Len. But, I want to sing a happy song this time. Also, I want to treasure his smile, the warmest smile in the world, with me until I die.

My fragile body...cursed me. My life had been worthless. I wanted to kill myself a million times. Well, that was before...before I met Len.

December 13th 1884, London

It was a stormy night when I first met him. My parents abandoned me since I was 8 years old because they had to spend so much money on curing my disease. Then, after spending 5.000 worthless Euros on curing my disease, they kicked me out of the house. I would be more than happy to get out of that cursed house and away from my horrible parents, of course. But they kickedme out! Their own flesh and blood! Me! I wasn't very happy about that.

My parents loved me, only because I could sing. They used my passion of singing and my voice for their own good. Fame and wealth. That's what they ever lived for. My parents were very cunning, evil, mischievous and stingy. But, worst of all was they used their own daughter to make money for them. And when their daughter was obviously dying, they gave up curing her and kicked her out of the house. When she was 8 years old for God's sake.

Since the day my parents kicked me out, I didn't consider myself as Kagamine Rin anymore. Rin. That's my name. No Kagamine anymore. Only Rin. I hated my parents, and I do not want to use theirfamily name as mine. But, I couldn't help but feel a pang of loneliness and longing. Deep down, I still loved my parents. Just a bit. Mother had given birth to me, and Father had cared for me and educated me in singing. But then, I suddenly remembered that Mother only kept me because once, she met a fortune-teller that said that Mother's daughter will be extremely talented in singing, and will bring good fortune for her and Father. So Mother kept me. If the fortune-teller hadn't told Mother that I would be useful for Mother and Father's fame and fortune, she would surely have gotten an abortion. She always thought that children are a pain and a waste of time and money. Time is money, that's what she always said. Well, that obviously incinerated this feeling of love inside me.

I slept under bridges, near a river, in an old, worn-out box and best of all, on a chair at the park. But, of course, I couldn't stay on the chair forever, especially at winter. I'll freeze to death if I did that. So, I decided that my permanent house would be the old, worn-out box I've been using for the past 4 years. I used a worn-out, but warm, blanket I found in the trash can. Well, it was still useable; there was only a huge ink spill at the middle of the blanket.

I was twelve then, and I have a fragile body. My disease wasn't any help either. The disease attacks my vital organs, and will eventually hit my brain and heart and I will die. And so, I waited for the time...the time when I wither.

For a living, I sang 3 times a week at the park and lots of people came to see me. About each person who came to see me gave me 5 Euros. And there were always about 35 people there every time I sang. So, I could make 175 Euros each time. I used some for food and kept the rest for emergencies and I saved up for a new house. I know it would take me ages to afford a house on my own at this rate, but at least I've found my reason for living.

But that's not enough. I need something to prove that I existed. A proof of my life. I don't just want to survive. I want to live and be acknowledgedof. This was practically impossible; I am a diseased peasant after all.

I haven't been singing because it was getting more painful every time I sang; I haven't eaten in 3 whole days!

Then, one day, a storm came. Well, that was lucky, wasn't it?

Anyway, I thought it was the worst storm I've ever seen in my life. But in fact, the storm was what led me to Len. Or what had probably led Len to me.

Once the storm ate away my one and only house, the old worn-out box, I walked away without any direction and tears in my eyes. Then, it hit me. It felt like my lungs were being ripped out, along with a hammer pounding my brain. I felt dizzy and immediately crumpled to the ground. With streaks of tears on my cheeks, I took in painful breaths.

One...two...three... One...two...three

I counted the painful breaths I took in. I had to make sure I got enough supply of oxygen, so that my brain wouldn't stop working. And of course, my brain and body refused to take the air in, but I willed my body to do so.

I can't take it anymore.

Every breath feels like sending a knife down your throat. So, I stopped breathing, even though I knew it was essential to me. Oh, well... I guess it's time for me to say good bye.

But I haven't got the chance to prove my existence.

I have no proof of life.

And so, I should not—no, could not die!

I took in another painful breath. And another one, and another... Until my vision blurred and my heart rate increased. I was sure I was going to die then... Until somebody picked me up, one arm supporting my back, and the other one behind my knees.

For a second, I saw a blonde boy, about my age. He has the same magnetic blue eyes like me. Although his face was more boyish, and his hair was tied up in a ponytail, his facial features looked a lot similar to mine.

"Hold on," he said.

"Who—"

But then, my vision blacked out.

20 minutes Before the Storm

"Be back before 7 okay, Len?"

"Yes, Mom," I said. "I'll be back before then."

I walked out of the mansion and headed for the bakery store. It opens until 9 PM.

I checked the watch on my wrist. It said '6:02', and since it'll probably take me about 15 minutes to walk to the bakery store, I'll be back to the mansion before 7. Mom insisted I should ride Excalibur, my horse, to the bakery, but I said that I'd like an evening walk. Besides, it was just a 15 minute walk.

2 minutes Before the Storm

After getting all the types of bread from the list my Mom gave me, I walked to the counter and paid.

"That'll be 100 Euros."

"Here you go, Luka," I said as I gave the shopkeeper-slash-childhood friend, Luka, 100 Euros.

"Well, thank you Len. Be careful on your way back."

"I will," I said with a flash of my smile. As I headed for the door, Luka stopped me.

"Wait, Len!"

I turned around. "What is it?" For a second there, I saw concern and doubt in Luka's eyes.

Yes, doubt. That was an expression Luka rarely has.

"The weather reporter said that there will be a storm coming in 30 minutes or so. So, run to the mansion Len!"

I smiled at Luka. I hadn't known Luka had an 'immature'side. All I needed was 15 minutes to walk back, so the storm won't be a problem. "I will Luka, thank you for the warning."

"Run, Len!"

I decided to ignore her.

I thought the storm won't be a problem. But, that wasbefore a huge wind blew my hat away, and hard rain droplets raked their sharp ends against my face. It had been only 2 minutes since I got out of the bakery. 2 minutes! Well, the weather reporter wasoften wrong.

Then, a huge storm fell crashing down onto the streets of London.

I ran to the mansion, holding on to my bag filled with different types of bread. So far, the storm blew away my hat and my yellow scarf. I am not going to let it blow away Mom's shopping bag.

I kept running, my chest heaving up and down. What I thought was a 15 minute walk, felt like a month of running. Just as I thought I would never get back home, I saw the mansion at the end of the road.

But then, I saw something else. Someone, to be precise.

A girl, about my age I think, was lying on the ground. I couldn't see the movement of her shoulders—which indicated no signs of her still breathing.

Panicked, I ran to her and lifted her up. I do not ignore somebody that needs help. She was quite light, and I headed back for the mansion, a girl and the shopping bag in my arms.

"Len, you're soaking wet! I'm so sorry, dear! If I knew a storm was coming, I would have never sent you to the bakery!"

"It's okay, Mom. Besides, you never listened to the weather reports."

Mom gave me a watery smile. Her eyes filled with tears. "I'll listen to the weather reports from now on dear."

I smiled. "No need Mom. The weather reporter is very often wrong."

She smiled faintly and nodded.

"How's the girl, Mom?" I said, trying to change the subject.

"She's fine dear. I changed her clothes," Mom said, a kind smile on her face. "How did you ever find her, Len?"

"I was running to the mansion when I saw her lying on the ground, so I brought her here. You don't mind, do you?"

She smiled and shook her head. "I don't mind at all, in fact I'm proud of you for taking her here in the first place."

"It wasn't that big of a problem," I said, a genuine smile stretched across my face.

"Still, I'm really, really proud of you, Len." Mom's face seemed worried. "It's your Dad I'm worried about. He would never let strangers into the house, let alone...orphans." Mom avoided using the word, 'peasant'. She always thought everyone as an equal; she hated the word 'peasant'.

While Dad, on the other hand, liked to mock peasants and respect the rich. He once threw Excalibur's...waste on top of a peasant and laughed at the seemingly funny joke.

Why did my Mom ever fall in love with that...guy?

Mom seemed to have read my mind.

"Your Dad once was a very kind man. He liked to treat others as equals. There were no…peasantsor rich peoplein his dictionary. Well, until his company got broke. He was drunk, his world turned completely around, and he started hating…those unlucky people."

Again, she didn't use the word that hurt her.

"But, it wasn't their fault, right?"

Mom looked at me with those sad eyes again, and shrugged. "Oh, dear, I don't know for sure. The 'unlucky ones' envied the wealth that my husband…had. Although he was a kind man, they stillenvied him of his wealth. And so, they released rats inside his company when a health inspector was in the building. And so, the company shut down."

I kept my mouth shut. It seems that Mom doesn't want me to remind her of that matter. So, I changed the topic. "I see. Anyway, Mom, may I check on the girl?"

Mom suddenly smiled and nodded, that sad look was long gone from her eyes. "She's inside the guest room."

I knocked on the guest room door and went in. The girl was still sleeping, breathing heavily. Fortunately, Mom is a doctor and she gave the girl some medicine so she'll breathe normally. I sat on the chair next to the bed. She looks just like me, except for the fact that she's a girl and I am a boy.

A filthy white ribbon was resting on top of her head and hairclips were neatly clipped on her hair. I took off the filthy white ribbon and washed it at the sink. I let it dry off near the sink and went back to the chair, waiting for her to wake up.

I woke up, finding myself on a very comfy bed. I tried to sit down, but my body ached and I immediately fell back down.

"Good. You're awake."

I looked to my right and saw a boy that looked just like me. He looked somewhat…familiar. I wrecked my brain, trying to find the memory of this boy. I thought deeply, and his voice, too, seemed familiar. Of course! He was the one that saved my life!

"Thank you, for saving my life," I said.

"You're welcome," he said with a gentle smile. "My name is Len, by the way. Kagamine Len."

My eyes widened in pure shock. He has the same family name I have—had. But, it was impossible. No way could he be related to me. He looked as old as me, and I don't remember having a brother. Maybe it was just a coincidence.

"My name is Rin."

He smiled. "And how do you feel now?"

"Fine," I said, returning the smile. "All better, thanks to you."

"Good," he said, a warm smile stretched along the lines of his face. Then, suddenly his smile faded into a worried frown.

"What's wrong?" I said.

"It's just that... I was just wondering...Why were you lying in the ground?"

I looked away. I didn't want to tell him about the disease, but then he did saved my life.

"I-it's alright if you don't want to tell me, Rin."

I smiled and shook my head. "Well, you see... I have a disease. It…it's called heart cancer."

Len's eyes widened in shock.

"Yes, I know. Terrifying right?" I said. "That's why I didn't want to tell you…"

Tears started to well up in my eyes. Len would surely want me out of the house now. After all, I amjust a diseased peasant that he took in. I'll just be a pain to him and his family... Although, deep down… I didn't want Len to kick me out. The feeling of being kicked out is too much to bear...

Len started to panic. "What's wrong Rin? Did I say something wrong?"

I shook my head in a 'no'.

"Then, what is it?"

"Y-you would surely want me out of the house now, r-right?" I stammered between sobs. Len lifted his eyebrows in confusion.

"Why would I want to do that, Rin?" he said. "I would never abandon you on the street."

My tears stopped instantly. "What do you mean?"

Len smiled. "My Mom is a doctor, she would surely cure you."

"So you mean..."

"Yes. You could stay with me until you've recovered."

My eyes flickered with joy. I hugged Len in delight. Yes, the sudden movement did hurt a bit, but what the heck. "Thank you, thank you, thank you!" I said.

Len smiled and hugged me back. "You're welcome."

Then, a deep voice came from the door.

"What do you mean, Len?"

Len broke the hug and turned around. His eyes widened in shock. "Da-dad…"

"What do you mean, she could stay with us?" Len's dad said.

"It-it's just that s-she…" Len stammered.

"She what, Len?"

Len gulped and took a deep breath, trying to compose himself. It's obvious that Len was frightened by his own father. "She's sick, Dad. She needs medical attention."

"Why can't her parents do it for her?" Len's dad said; his voice deep and frightening. Len didn't know what else to say. Well, Len didn't, but I did.

"My parents disowned me," I said. As I said that, both Len and his father kept quiet and turned around to look at me, the weak girl sitting up on the bed. "I am sick, Mr. Kagamine. Sick with a deadly disease. My parents gave up curing me and threw me to the streets when I was 8 years old. I lived in a worn-out box for the past 4 years. But, my box was destroyed in the storm, so I do not have a home to stay in, nor do I have parents to love me." I gave a quick glance at Len and then to his father. For a second there, I thought I saw pity in Mr. Kagamine's eyes. But, that was just an illusion.

"I don't care if you die on the street. Just get out of my house!"

I felt my heart sank to the bottom of my stomach.

"Please, Dad! Let her—"

"Be quiet Len! What do you know about this cruel world? You're just a naïve kid!"

Well, Len's dad was stubborn. In that case, the only thing I could do was to use my trump card.

I stepped out of the bed, losing my balance for a second and quickly grabbed the edge of the bed for support. I locked eyes with Mr. Kagamine's blue eyes, and gave him the most serious look I could muster. "I could sing," I said. "You could use me for your fame...and wealth."

Mr. Kagamine's eyes perked up in joy at the word 'wealth'. Wealth, that's all adults could think of.

"Then, sing for me girl."

I nodded and opened my mouth to sing a song I made, 'Proof of Life'. It hurts every time I sang, but I have to hold it.

"The wind's voice tells me of winter

My body shivers as I listen

You're right next to me

Your breath seems white and cold…

Life has withered away, too, this year

Before long, I've grown impatient for spring's arrival

While listening to the chains of life

Continuing to bud in the light...

My fate continues to rot away

I understand, but I remain strong

I want to breathe, I want to sing

It would be good if I can leave something behind

That says I have lived… a proof of my life

I don't want to sing a sad song

Hey, I'm begging you, right now my only wish

Is to laugh next to you

I want to sing a gentle song

Several winters passed by

I finally realized this feeling

I can't say it out loud but

Our hearts are always connected, right?

It's dark, I can't see anything…

I can't hear anything…

It's scary…

It's painful…

It's lonely…

While everything in me

Continues to disappear

Your smiling face

Still lingers…

You are singing a gentle song, right?

Even though we're wrapped up in this world of loneliness

I'm always beside you, don't forget

You are never alone

I'm not lonely because you're here

You embrace with your warm hands

I can't hear you, but I understand

The hands that you hold me said "I love you"

I do not want to sing a sad song

Hey, I'm begging you, my only wish right now

Is to laugh with you

I want to sing a gentle song

I want to dedicate it to you, a song of parting

In my last moment, I want to tell you…"

I looked at Len, and spoke the last word of my song. "...thank you."

Len smiled and nodded. I could see his eyes glistened with suppressed sadness. I myself have got to admit that my song really was sad. At least, Len was still being a man. His father was crying like a lost baby.

"Y-you don't have to pay f-for the medical attention we're going to give y-you. You could stay here for as long as you want. As long as you sing me that song one more t-time," Len's father said between sobs. I showed my pearly smile at Len. He smiled back and I started singing once more.

Author's Note: That's all for now! And yes. Len's dad has mood swings issues.
