I tried the key card again. The door refused to open. Damn it. I pounded on the door and prayed Casey would wake up.

"Casey? Open up! I know you're in there!" I yelled. My sister was probably sleeping her head off by now. It was 12 AM and I didn't blame her for sleeping. But the beach party was too awesome for me to leave early… I kicked the door in frustration and glared at my key card. Stupid card. Stupid hotels.

Then an idea dawned on me. Maybe this wasn't our room. Maybe it was my parents'. Their room was near ours, and they were out for the night! Bingo! Now to open the right room. But was our room 1216 or 1219? I couldn't remember. I should have paid more attention.

I tried my key card on room 1216. No harm in trying. The door didn't budge. No sound whatsoever. So it was across! Here I come, 1219.

I tried the key card and pressed on the handle. It was still locked. I took a deep breath. Maybe one more time. I tried again.

Click.

YES!! It opened. I swear I'm never going to go partying on a vacation again unless I have a companion who knew how these stupid key cards worked. I opened the door.

What I expected was my sister snoring on the bed.

What I saw was a guy coming out of the bathroom dripping wet, with only a towel wrapped around his lower half. I stepped backward involuntarily.

For a few moments, I was speechless. He glanced at me and seemed every bit as shocked as I was.

"What are you doing here?" I demanded.

Had my little sister been taken advantage of by this…sixteen, seventeen year old? She was fourteen, so I supposed it wasn't that big a deal, but still! She might have been drunk! Okay, maybe not. Casey didn't drink. Maybe she brought him to our room of her own free will. But Casey was squeaky clean! This wasn't like her! Then again, he was hot...

No, no. That's beside the point. Focus, Aiden, focus. The point is, a guy is in our room and my sister just came from a beach party I dragged her to. I was a bad sister.

He blinked and looked at me. His gray eyes were adorable. "This is my room."

"What?"

I opened the wrong room? But the key card worked…I glanced at the white card in my hand incredulously. Then I looked at him. Oh God. The chances of this being his room were way bigger than the chances of him being Casey's boy toy. And I had yelled at him.

"I'm really sorry, I thought…This card opened the room."

He snickered. "Right."

He didn't believe me?! What did he think I was? Some sort of sick perverted stalker?

"I wasn't trying to come in! But if you're going to be an ass about it, then I'm not all that sorry after all!" I stormed out of the room and back to our room, room 1216. I banged my fist on the door.

"CASEY, OPEN THE DOOR RIGHT NOW!" I was steamed. I tried the handle again. It wouldn't budge.

"What is wrong with you? You open the wrong door for me but you won't open the right one?" I hissed at the card. I pulled out my cell and dialed Casey's number. Come on…pick up.

Beep. Beep.

Busy? What could be more important than her sister being locked out of her room at 12:30 AM?

Out of the corner of my eye, I saw mystery jerk leaning on the doorframe and smirking. Stupid egotistic maniac. I didn't mean to open his door! At least this time he was wearing shorts and a shirt.

"Why don't you try my key card?" He asked.

Ha. Never. Not after what he said. I tried my key card again. It still wouldn't work! Why in the world…? I pounded on the door again. "CASEY, WAKE UP!"

"You're going to wake the dead with all the noise you're making."

Couldn't he just leave me alone? I glared at my key card. This was all its fault. I walked towards the elevator and jabbed the down button. I might as well go to the reception and ask for help there. I tapped my foot.

Click.

"Your door's open."

I glared at him and stomped into my room. "Thank you."

He laughed. "You're adorable when you're angry. Look, I believe you. These cards sometimes go wrong."

I looked at him. Blond haired and gray eyed. Tall and lean. I suppose it was partly my fault. "We're even."

He raised an eyebrow. "Excuse me? You walked into my room, screamed at me and I opened your door. I only insulted you once. You still owe me two."

Owed him two?

I slammed the door in his face. Stupid jerk. I looked at the bed. Where was Casey anyway? Didn't she say she'd wait here in the hotel room for me? I called her cell again. This time, the operator answered me. I sighed and flopped down on my bed, praying she was all right. What if something happened to her? I shouldn't have brought her to the party. Hell, I shouldn't have gone to the party in the first place.

When I woke up the next morning, Casey was fawning over a breakfast sent to our room.

"I didn't know you ordered room service, Aiden! Mom and dad are going to make you pay for this!" She giggled.

"Shut up, Case. Where were you last night?" I couldn't say I hated the food. Everything I wanted - and loved - was on it. But I sure as hell didn't order it.

"I went for a walk in a more quiet part of the beach. It's dangerous walking around alone, I know. But you can't tell mom and dad. Or I'll tell them you were drinking last night. And that you brought me with you."

"Case, I'm sixteen."

"So? I'm fourteen."

I sighed and rolled my eyes. She was right. Our parents would kill me. I turned to the food and began to choose my breakfast. Pancakes? Looks like a winner! I noticed an envelope on the tray. I opened it and read the note inside.

Dear Ms. Campbell,

This breakfast is on me. I hope you like it. Order anything else you want, tell them to put it on Room 1219. No hard feeling about last night, is it?

If this is Casey, give it to your roommate. She screamed loud enough to wake all of Florida last night trying to get you to open the door.

P.S.

You owe me three now.

I crumpled the letter. Three? Ha. I probably won't ever see him ever again. His three favors are flying out the window because we were going back home to New Jersey today. Take that, you jerk.
