A/N: So, I got this idea while being awake at 3am in the morning, just like I am every night while my winter holidays. Enjoy, and excuse me for making any mistakes.

Seto's P.O.V.

It was a day just like every other was. Wake up, go to school, go to work, come home late, maybe spent some time with Mokuba, and then go to sleep. And tomorrow all over again. Well, sure as hell, tonight I won't spent any time with Mokuba. It's way too late and he was probably long ago asleep. I enjoyed sight of asleep city passing by as I sat in my limo, waiting to finally get home. After some time, it actually did happen. I waited for my driver to open the doors. As he did, I started walking towards my mansion, leaving him to take care of limo. I unlocked and opened big heavy doors, trying so hard to be as quiet as I can, not wanting to wake up Mokuba. After I locked the doors behind me, I started walking towards living room and kitchen, wanting to dinner. I almost fell over something purple as I trapped. As I got back my balance, I looked down at what was lying on the floor. It was a purple suitcase. And around that one were many others. But who would left… Oh no, she didn't! I knew only one person in the whole universe that could be this messy. And only one person who would be brave enough to leave this mess in my living room. But that person was supposed to be in New York. Or Paris. Or London. Or Tokyo. Or anywhere else but here. I wasn't actually sure, she moved a lot. I don't know if she ever stayed anywhere longer than a year. She travelled the whole world about three times, and it was expensive. But I didn't mind it as long as she stayed a hell or two away from this city and Mokuba and me. Don't get me wrong, I love my sister… Well, at least I think I do. The thing is that we are like fire and ice. And she's the fire. She's a big dreamer. Day dreamer. She's smart, yes, but while I'm learning and trying to improve myself and run the company, she just party at the night, sleeps until afternoon, goes to shopping, and dreams about her Prince Charming. Yup, Prince Charming. Since she was a little kid she had some dreams about some guy who's face she had never seen, and since then, she's in love with him. She told me that sometimes they talk about some random stuff. Well, at least it was like that before, when we actually talked to each other. Now, I'm not actually sure about her still waiting for Prince Charming. Maybe she even found him. Or something close to it. I mean, I know she dated that K. guy, who's whole name I couldn't remember, for some time when I last time saw her. But I have no idea how thing between them ended. If they broke up, well then I'd be the happiest older brother in the world. Not that I'm some overprotecting brother, but that guy was a trouble. He had no future, but he had tattoos, and was four years older than her. So, she was fourteen and he eighteen. I tried to forbid her to date him, but that was a bad move. She was stubborn and when someone tried to forbid her something, well, she then definitely did it. I remember that fight quite well.

FLASHBACK

It was after some tournament in New York. Back in that time, she was living in penthouse in Manhattan. Mokuba was travelling with me, and she decided to invite us for dinner, and to meet her boyfriend. News that she actually had one was shocking. I was thinking of all the things I could say or do to broke them apart as we rode to her apartment. She was only fourteen, for God's sake! The fact that I've let her live on her own with only three bodyguards and travels the world was already hard enough for me. But let's face it, it was easier this way. We've always fighted, since we were children. She was one year younger than me, but we were totally different. We were both intelligent, but as I did everything to run the company good, she did everything she wanted. We finally came in front of her doors, and I knocked. After some time doors swung open, and behind them was a teen girl with straight brown hair and blue eyes. She smiled as she saw us, and so did Mokuba.

-Sis!- He yelled as he runned towards her and hugged her. I just stepped inside.

-Nice to see you too, Seto.- She said sarcastically as she kissed me on the cheek.

-Don't even try, I've heard of yours not so good grades. I think you'll have to pause with shopping until they are only A's.- I said, remembering her principal calling me two days ago.

-What?!- She yelled following me into her living room. I stepped in the first, and I almost faded. There, on the white couch , a guy with long black hair and many tattoos, in black gym suit and grey shirt with straps. He had his legs crossed at a little glass table and a beer in his hands.

-C'mon! You crap of a player!- He yelled at the TV. My sister cleared her throat, and the guy looked at us. He cleaned up his chin with his hand, and then held it out for me.-Hey dude! I'm Kol, you gotta be my kitten's bro!- He said, and then looked at Mokuba, who looked almost as disgusted as I.-Hey kid! What's up?- Mokuba faked a smile, and I just glared at my sister. She gave me that 'just-give-him-a-chance' look, and I nodded towards Kol.

-Seto.- I said, and he took a hand, and moved his hand out of my sight.

-Dinner will be ready soon. And, Kol, you could go find some wine.- I glared at her again, not believing my ears. She was fourteen and she has alcohol in her apartment.

-Got it babe! Hey, kid, why don't you come with me?- He asked Mokuba, who looked at me, and I nodded. Finally, we were left alone.

-What the hell is wrong with you?!- I almost yelled at her.

-I know he doesn't look like a good guy, but he is. Really. Just give him a chance, you won't regret it, I promise.- She said.

-I wasn't talking just about your new boyfriend. I was talking about your grades and you skipping classes. This is not you. C'mon, you're smarter than that!- I said. She looked at me, eyes wide open, probably surprised me knowing everything.

-Maybe I'm just tired of being a little perfect girl! Maybe I want to actually try this life and enjoy in it! Maybe I don't want to be like you and to spend my whole life with computers!-She yelled at me. Yes, yelled.

-Life is not destroying your own future for something that will pass!- Now I was yelling at her. She was about to say something, when Kol interrupted us.

-Wow, chill out, you two.- He said.-Dinner is ready.- We all sat at the long glass table, me on one side, my sister on the oher side, and Mokuba and Kol between us. The whole dinner was one big awkward silence. But then her and Mokuba went somewhere, and me and Kol were left alone. Just what I wanted.

-So, Kol, you're on collage?- I asked him.

-Nah, I ended high school and don't see any need for doing anything more.- He said and took a big sip of the wine that I forbidden my sister to drink. She tried to protest, but there was no point.

-So, you like my sister?- I asked him, not even trying to hide how disgusted I was.

-Totally.- He answered.

-You're really cute couple. Too bad you'll break up.- I said, and he glared at me.

-Excuse me?- He raised an eyebrow.

-Well, she never stays anywhere for long. And when she travels, she travels alone. Even if she decides that she wants to bring you with herself to her next destination, I won't allow it, and I'll make her chose between you and being free. We both know what she will choose. But, I'm giving you a chance. Break up with her after me and Mokuba leave tonight, and I'll pay you two millions dollars.- I said and took a sip of my wine. Kol was about to answer me, but someone cut him off.

-How dare you?!- Yelled a familiar voice, and as I turned around, I was faced with angry face of my sister.

-Oh, good. You're here too, so you can hear how amazing and loyal boyfriend you have.- I said sarcastically. I expected her to shout or scream or yell at me, but she just stayed silent for few moments, until she finally spoken.

-Leave. Now.- She said, almost whispering, with tears in her eyes.

-With pleasure. Mokuba.- I said looking at her.

-But…- He started, but I cut him off.

-Now!- I said and he followed me out of our sister's apartment. It hurted me to see her cry, and even worse was knowing that I was the one who's fault it was.

FLASHBACK ENDS

And that was the very last time we saw her, almost a year ago. I walked towards kitchen, and then a small crashing sound was heard. It resounded trough empty mansion and I was afraid that will wake Mokuba up.

-Can't you at least try and be silent?- I asked as I reached the doorstep. She jumped a little and turned around to face me. She was wearing black leggings, a little bit oversized icy blue t-shirt with a big Mickey Mouse picture on it. Did I mention how childish she was?

-Seto.- She smiled.

-Katherine, I didn't expect to see you.- I smiled back.

A/N So, what do you say? Should I continue? Please, review and tell me :D
