Hey everyone! So I have become obsessed with LenXRin, and I have to write about them or my fangirl emotions may explode everywhere. I've been hooked on their music ( mostly Len, but them together is just so amazing. ) and I just wish there were more, and better fanfictions about them and their love for each other. I ship them reeeaaalllyy hard, and I plan to write several more fanfics about them, some of them based off some of their songs, like this one.

Adolescence is freaking amazing, by the way. I highly recommend you watch one of the versions on Youtube if you haven't, as it's super awesome romance, but they just weren't enough for me. Just kiss and get together you two, seriously!

Oops, haha, too long of a note! Anyway, hope you enjoy, and if you don't like the pairing of RinXLen as brother/sister, don't read!

I hope I did the pairing justice.

Have fun!

Rin's POV

Len and I are probably the perfect image of brother and sister. We barely fight, and when we do it's all playfully, the effects never lasting long as one of us always gives in to the other. When we sing together, our voices blend perfectly, and we always sound better together. ( Though Len's voice is much better than mine, in my opinion, though he always disagrees.) We look very alike, mirror-images of each other really, with our shining gold hair and deep blue eyes. Though, the more I look into Len's eyes, the more I notice how when he's feeling upset or confused, or affected by something, his handsome orbs go from cerulean to a much darker than mine night blue.

I've found I've been doing that more lately... just gazing at him, at his cute smile, the way his jaw tenses when he thinks, the slight way he brightens when we're together like always, playing games and having fun, how his tone goes dark when he's protecting me. He's the best brother I could ever have.

But... I wish we weren't related. Maybe then I wouldn't feel so horrible when I'm with him. You see... My brother Len... I... I'm in love with him. I love him not as a sister should. I love him the way a woman loves a man, or a regular teenage girl falls for a boy. I'm in love with my brother.

I know it's wrong. I shouldn't think this way, it's terrible, and it could ruin the relationship I have with my brother. To even speak of it is forbidden. I can't help how I feel towards him, however.

Len and I played so much together when were little. We slept in the same room for most of our lives. We care for each other more than we care for anyone else. But, hidden under our family bond lies a deep undercurrent of something else. Lately, I've noticed more and more how the way we act around each other is changing. Before, I never would have given the slight changes any heed, but ever since I've come to the realization that I care deeply for him, I've picked up on certain differences. How I catch him watching me when he thinks I'm not looking. How, if we brush hands now, it sends a rush of warmth into my entire body and causes the two of us to blush and look away. The air between us no longer holds the easy air of brother and sister, but the thick tension of something more, something we're both afraid of, and yet I can't help myself.

Every time we're together I want to say the words, but they just get stuck in my throat as a painful lump. I want to be able to reach out and brush his hair away from his face when it falls in his eyes, I want to hug him close and never let him go. I want to hold his hand, and be his perfect match.

I think our parents have picked up on the changes between the two of us. Tonight, they're making Len move into the room across the hall from mine, saying we're too old to stay in the same room anymore. It's a tactic to keep Len and I away from each other, we both know this, but we can't go against their wishes. Lately, we've barely been able to spend any time together. That's why I was surprised Len came to my room to talk and play with me tonight like usual, even though he'll have to go.

We act as if everything's normal, but even as we play and laugh ordinarily, our eyes catch several times. I can't do anything about how my gaze is drawn to him. He's like a magnet, and I'm constantly pulled towards him...

As the night grows later, I dread the thought of sleeping alone in the room big enough for the both of us. Len always kept the bad dreams away. Whenever I had a nightmare, he would get into bed with me and hold me tightly, kissing my forehead and telling me everything would be alright. Only after he was with me would I be able to sleep. Without him, how will I get through the night?

We laugh together. I smile at him, and my hand involuntarily reaches for his while I talk. At the contact, his smile vanishes, and I see a light blush stain his cheeks. I know I have accidentally crossed a line. For a moment we both say nothing, before he stands.

" It's getting late, Rin. It was nice to spend time with you," He says, offering his handsome smile my way.

" Must we really sleep in two different beds?" I ask him sadly, looking up at him, the pain audible in my voice, my disappointment that this is how it has to be clear in my tone.

He just smiles at me. " Good night." Len says quietly, heading for the door.

As his hand reaches for the doorknob, my heart beat picks up with fear and sudden panic. I don't want him to go yet...!

Before I even know what I'm doing, I've jumped off the bed, my lace nightgown fluttering around me as I run to him and grab the untucked edge of his white buttoned shirt, making him pause, his fingers inches from the door. " Rin...?"

" I..." I fight for words, not able to make any come out.

I let go of his shirt then, and he turns around to face me. To my surprise, without a word he bends down to one knee, taking my right hand in his and lightly kissing the tips of my fingers. The contact of his lips on my skin makes me draw in a quick breath, and my face burns. I can see his own face, dusted red like my own. At that moment, I think we both felt something strange pass through us, something unspoken.

" Don't worry... I'm always nearby." Len says against my fingers, standing straight and, while with that same smile, finally letting go of my hand, turning away.

He opens the door, reaching to the light switch, and I feel strange, filled with emotion... I can't let him go! To be in the dark like this, alone... Especially when I want him beside me so, like we always have been... The thought of being alone is unbearable!

My footsteps alert him to my presence, and as he turns to look, I throw myself into his open arms, wrapping my own around his torso tightly and making him stagger slightly, bumping into and closing the door. My face is bright red, and I dare not look up at him yet, at his startled expression.

" Don't t-turn off the light..." I say in a whisper, face buried in his brown vest, inhaling his spicy, warm scent while my hands grasp the back of his shirt tightly. " I'll be sleeping alone tonight... But, I don't want to yet!" I say with anger, knowing I'm acting silly.

" Aren't you a bit old to be afraid of the dark, my princess?" I finally look up at him, at the teasing tone of voice he has. He's smiling down at me, but his eyes portray something hidden.

I can't help it; my eyes fill with tears. Tears of frustration, of hurt. I want desperately for Len to hold me, to hug me back instead of stand there hesitantly. I want to lean up and kiss him, I want to knot my fingers in his hair, I want to sleep with him next to me, protecting me! And he's clueless, or so he acts... How badly I want to tell him how I feel! And now we're to be separated, locked away in two different rooms, unable to spend time together like Mom and Dad used to let us... It's like a distant dream now...

As I gaze at him, my unspoken confession written over my face and my lips quivering slightly, I watch as my dear brother stares back. Our eyes lock, and I can see the emotions flitting across his expression. Slowly, Len's smile disappears, and conflict takes over.

I shouldn't do this to him, I think sadly, the tears nearly cresting onto my cheeks. To push him this way... It's wrong. I need to let go, I need to step back from him, stop this before it goes to far. My Len... I can't...

Suddenly his arms wrap around me, crushing me to him in a surprising embrace. I'm lifted from the floor into Len's arms, and just as quickly I'm pushed onto my bed. My head meets the fluffy pillow, and my eyes, which had closed in the surprising move, open to look up into the darkest and most beautiful blue I've ever seen. Len is looking down at me, his gold bangs framing his face, his arms on either side of me, my right hand and his left intertwined, barely a few inches between his serious face and my own. I can feel all of his warmth against me, and my heart, which had been beating very fast before, now feels as if it wants to jump out of my chest.

Silently, we gaze at each other, both of us still, willing the other to make the first move. This is the moment I've wanted for so long, and yet, it still feels wrong. Our childhood, our bonds as brother and sister rain down on us, making us remember all the reasons this shouldn't happen.

Len gazes at me steadily, and his fingers tighten around mine. Slowly, he leans down toward me...

... and I reach up with my free hand and brush my fingertips across his cheek, stilling his movement.

Despite my inner desire to allow him to kiss me, I know in my heart that I cannot let this go on. A foolish child is what I am, for even putting him in this position. My dear, sweet twin brother...

" I'm sorry." The words hesitantly bubble from my lips, and I smile up at him, a smile of resignation and longing, my face written with everything I've felt towards him, everything I cannot say.

His gleaming eyes widen, and then he, too, smiles back at me. He knows as well as I do that this isn't what we should do. In his eyes, I can see it... the unspoken feelings between us both. With that knowledge alone, I feel just a bit happier. He knows this isn't rejection... It is only how it must be.

Oh, how despairing I feel inside! I would love to lean up, continue where we left off... but I cannot.

He gets off of me, sitting instead on the edge of my bed, and I sit up to face him, missing the heat of his presence the moment it's gone. Len brushes a stray tear from my cheek as it rolls down unbidden. " Rin..." He murmurs, hugging me again, but this time less passionately.

" Please... stay with me. Stay until I fall asleep." My hoarse voice pleads with him even as I regret the selfishness of the words.

" I will. " Len promises, brushing a stray strand of hair from my face as he pulls away. His smile is still there, but I can sense his emotions underneath.

He tucks me back in, and lays beside me. I curl up with my head on his chest, and his nearness and comforting aura makes me feel the drowsiness of the late hour and the events of the day, even though I didn't think it possible for me to sleep after...that.

As my heartbeat slows and my breathing becomes regular, and sleep has almost claimed me, I feel my brother shift from my side and sit up. I do not move, not wanting to let him know I'm still awake.

He sits at my side a few moments, and I feel the slightest touch of hesitant fingers on my face, stroking my cheek tenderly. I feel myself tense slightly, and I fear because of this, he knows I'm awake. As he does not withdraw his hand, I take that as a sign he doesn't realize yet and let out a soft breath of relief.

In the next second, I lose my entire train of thought and focus, as something warm and soft is pressed to my lips, gently, light as a feather, but definitely very real and very there. Len...?! Could it be? Did Len just...?

Before I have time to recover or react to what's happening, it ends, and I hear his footsteps retreat to the door quickly, closing it quietly as not to wake me, I'm sure. The moment he's gone, I open my eyes, sitting up with the blanket pressed to my chest, scarlet coloring my cheeks.

Len just... kissed me.

There's no way I'll be able to sleep after this.

Author's Note: Omg, I love this pairing ooooh so much! I wrote this in two days, because I am obsessed. I really hope you enjoyed reading it, and please tell me if it's good or bad, and if I should write more like this? Also, I was thinking I would do this, but in Len's perspective? Should I? Feedback is appreciated, and I freakin' love reviews, so if you could, drop one to at least tell me if you liked it or not! I have more fics involving these two planned, so stay tuned!

I'll edit it if anything is amiss or whatnot!
