Summary: Derek, Casey, Emily and Sam get locked in the school library after hours. Slightly based off "The Breakfast Club". Dasey!

He couldn't believe it. This was supposed to be one of the best nights of his life. He thought that nothing could bring him down. And then, of course, Casey had ruined it. The hockey team had just won their last game, completing their winning streak. They had won every single game this season. And because of this, Kendra was throwing a huge party in their honor. This was great for his rep. Girls already hung around him constantly, but now every eye in the room would be on him.

Unfortunately, he was stuck with the task of driving Casey. She had taken ages to get ready and he couldn't take it anymore.

"Princess you better get your butt out here in the next ten seconds or I'm leaving without you." He shouted through her bedroom door.

"Der-ek!" She shouted back, he voice dripping with annoyance. However she, reluctantly, came out.

And Derek wished she had stayed inside. She was wearing a tight pink tank top and a short jean skirt. And he wasn't sure what she had done to her hair, but it was sexy as hell.

CASEY

Tonight was the night of Kendra's big party for the hockey team. Ugh, as if Derek needs another ego boost. I mean he has his nice moments, but those happen about once in a blue moon. And now he was going to have a whole night in his honor. Well, it was actually in honor of the whole team, but of course, Derek didn't see it that way.

I had put on my favorite pink tank and a cute new skirt. I had curled my hair, but only slightly because I didn't want it to be too short. I was putting my home work into my bag so that I didn't forget it on Monday (I was already done) when Derek pounded on my door, rather rudely, and yelled,

"Princess you better get your butt out here in the next ten seconds or I'm leaving without you."

Did he always have to be so unpleasant? It was like it was his goal in life to be my enemy. We are polar opposites, Derek and I. We fight about everything, from schoolwork to the TV remote to our siblings to our friends. Sometimes I feel like my life is a never ending fight with Derek. Like, we will be seventy and in the same nursing home fighting over what color yarn to use when knitting hats for our children. Our children? Woah! I didn't mean it like that. Not our children together, separate children. That was weird it thought to myself as I opened the door.

I felt a small pang in my chest when I saw Derek. He had actually put some effort into his appearance. He was wearing his usual leather jacket, but with a nicer, cleaner shirt underneath. He wore a belt with his pants and shoes that weren't a million years old. And, I think, his hair might have some product in it? Wow, he really wants to get laid tonight I thought to myself.

For a second, I thought I saw him looking back at me with…..longing? But, just as soon as I'd seen it, it was gone. I decided not to dwell on it. Derek may seem quite simple, but in the time I have known him he has shown that he is more complex than he lets on.

"Well? Are you just gonna stand there with that stupid look on your face or are we gonna go to my party?" He said, effectively ruining the moment.

"Derek, this isn't your party! It is Kendra's party and she is throwing it for the entire hockey team!" I sniped back.

"Ouch, ya know, that really hurts Casey." He replied. I rolled my eyes, could he be more immature?

DEREK

A wave of relieve washed over me as we got into the car. Now, all I needed to do was keep my eyes on the road. Because, if I looked at the person I was thinking about in the very back of my head, I would surely crash the car. In a matter of minutes, we had picked up Emily and Sam. The conversation about how everyone was going to be at my party helped take my mind off her.

"Oh shoot! Derek I forgot my chem text book in my locker!" Casey said.

"Well too bad Space Case, there is no way I am stopping this car." I said rather smugly.

"Aww, c'mon Derek! It's even on the way!" She wined to my amusement.

"C'mon dude, it'll only take a sec." Sam said.

"Yeah Derek!" Emily complained, "Just let her get her book."

"Alright, Alright! No need to gang up on me, we'll go! But only for one minute." Derek said in an irritated tone.

They all got out and went up to the school. Unfortunately, the door was locked.

"Now what do we do?" Casey asked.

"Follow me." Derek said while walking around the school. They ended up at some unlocked, unmarked door that led to the basement. Derek led them through the hallways and straight to Casey's locker.

"God, I don't even wanna know how you knew that door was there, much less how to get out of the basement." Casey grumbled.

After Casey got her book they walked down the south hallway to leave. But Derek couldn't resist. Being in school like this, with all the lights off and no teachers? It was just too cool. He had heard a rumor, just earlier that week that the teachers kept all the answers to all their tests in the room in the library marked, Teachers Only. And he really needed to pass his English test next week.

"Hey guys, lets go to the library I have an, uh… overdue book." Derek said while walking in.

"Ugh, Der-ek!" Casey exclaimed, but followed him in with Sam and Emily trailing behind.

After trying the secret door many times and finally accepting that it was locked, Derek gave up and went to leave. But when he turned the knob nothing happened. He did it again and again and again, before finally saying,

"Uh, guys? We're locked in."
