I'm just a girl who
kissed a boy who
is in love with someone else
I didn't mean to
feel the way i do
it just happened by itself

Gabriella Montez chewed her lip worriedly the next morning, walking slowly down the East High, staring at the floor. Only one thought had consciously been on her mind for the last 12 hours: What did I do…?

She miraculously made it to her locker and numbly spun her combination, trying to clear the fog in her mind so she could get the right books out.

"Yo Troy!" Someone yelled from behind her and Gabriella jumped a mile and tried to melt into her locker. She cautiously turned her head and saw the one and only Troy Bolton swaggering as only the school's basket ball star could swagger down the hallway, surrounded, per usual, by his posse.

His eyes briefly met her face and she blushed and quickly dropped her eyes back into her locker, hoping to disappear.

"Troy!" Gabriella, if possible, felt even more frozen when she heard the oh so familiar trill of a certain blonde who was currently entangled in a passionate kiss with Troy.

Gabriella slammed her locker shut and slid into her homeroom quietly. She sat down behind Ryan as usual and kept her head ducked so when Troy and Sharpay came in, she wouldn't have to torture herself by looking at them.

Flashes of last night were flickering like an old movie in her mind and she shut her eyes and rested her head on her desk.

Gabriella… He had murmured, her name sealing their lips together; he tasted like cinnamon. Gabriella was too shocked to do anything but kiss him back, letting his hot mouth send tingles down her spine.

And now I'm sick inside
yeah, it makes me wanna cry
I'm so sorry about last night
yeah, it happened so fast
I wanted it to last
in the moment it felt so right
but now I'm sick inside

Sharpay giggled as she tossed a note to Troy when Ms. Darbus wasn't looking. Troy opened the note, grinned and wrote a response back, flicking it to her.

"Ms. Montez, there is no sleeping in my class! Head up, now!" Ms. Darbus barked, clapping her hands and causing Gabriella to jump. She blinked rapidly and watching Troy and Sharpay sneaking flirtatious glances between each other.

I'm a dirty mistress…I kiss another girl's boyfriend…I kissed Sharpay Evan's boyfriend… Gabriella thought miserably, feeling nausea swell inside her. She had felt feverish ever since last night, and not in the swoopy, twitipated way from Bambi but in the 'I could possibly throw up all over the place at any second because I feel so guilty' way.

Gabriella began chewing her nails as she absently took notes of Ms. Darbus' lecture; she was doing everything to keep from watching Sharpay guiltily.

"It's a beautiful night," He had murmured, "It matches the beauty in front of me." Gabriella was still shivering from the way he had sounded when he had spoken to her; his voice had caressed her soul and she had stupidly believed he really loved her.

"Gabriella…" She had been drunk of the moment, blind to the truth.

He stopped by my house
we were hanging out
he was wondering were you are
we went walking
we were just talking
then he kissed me by his car

When the bell rang, Gabriella stood up and began walking through the hallway, going to her next class. She sat down next to Taylor, her eyes boring into the back of Troy's head.

Why? Why are you doing this to me?! She mentally screamed at him.

"Gabby, Troy's here." Her mom had called.

"Troy? Why...?" She asked herself, bounding down the steps. Troy really was there, standing in her front foyer, grinning a lopsided grin.

"Troy, what are you doing here?" The brunette had asked incredulously.

"Can't a guy hang out with his favorite co-star?" Troy was always saying these things, even though Gabriella wanted to shout: "You have Sharpay Evans!"

"I, uh, don't see why not…Wanna watch a movie?" Gabriella was socially awkward, she always had been. She usually made a fool of herself just trying to make popcorn.

"Sure." She and Troy ended up sitting on her bed but he wasn't watching the movie, he was looking at the pictures around Gabriella's room.

"Do you know what Shar's doing tonight?" The good thing about Troy was he actually was a good actor; he could feign nonchalance like no other teenage boy Gabriella had met.

"No, I'm not her keeper." Gabriella didn't mean to sound bitter; she just wished everything wasn't always about Sharpay.

"You're right, I'm sorry, I shouldn't have mentioned her." So slick, Troy. Never let 'em see you sweat.

Gabriella came back into the present when her science teacher accidentally exploded a beaker. Gabriella found herself jumping in fright and ending up on the floor.

"Gabriella, are you alright?" Taylor asked, looking around embarrassedly as she helped the curly haired genius up.

No. "Yeah, sorry." Gabriella's face was on fire, Troy was watching her.

She turned her head, pretending to be adjusting her ponytail and caught Ryan's eye. Ryan gave her a small smile then shifted his eyes back to the teacher.

Gabriella grimaced at him and turned back so she was facing front. She looked up just in time to see Troy running his fingers through his hair, much like last night when they'd ended up walking around her street.

"I just don't see how atoms could do that!" Troy insisted, merely making conversation.

"That's because you're a simple minded creature." Gabriella taunted, feeling like a five year old.

"Or you're a complex minded creature!" Troy shot back.

Somehow, they were in front of her house, standing near his car. Gabriella cleared her throat and looked down at her feet, suddenly feeling awkward.

Was this the end of the night? Do I just say goodnight and go back inside? She thought helplessly.

Gabriella leaned against his car, her head spinning with these wild ideas so much she didn't notice that Troy had his body facing her now. Gabriella took a small step backwards and Troy took a larger step forwards so he was not even in inch away from her.

"Gabriella…" Troy had his hand cupping the side of her face, tilting it up so they were kissing before she knew what was happening. Gabriella knew it was wrong, she knew she should stop but it was like a child's tongue to a cold pole, she couldn't pull away.

Troy brought his hands into her hair and she hesitantly wrapped them around his neck. When he pulled away, Gabriella couldn't breathe.

Troy just looked at her for a few moments then silently turned and got into his car. Gabriella stood on the side of the road, watching his taillights fade in the night.

And now I'm sick inside
yeah, it makes me wanna cry
I'm so sorry about last night
yeah, it happened so fast
I wanted it to last
in the moment it felt so right
but now I'm sick inside

During lunch, Gabriella sat with them. She couldn't bring herself to say anything to Sharpay and she didn't dare look at Troy. Instead, she stared at her unappetizing food and pretended to eat while Troy and Chad had an impromptu 'who can throw their tray the farthest' competition.

"Gabby, why aren't you eating?" Taylor asked concernedly.

"What?" Gabriella turned to Taylor, shaking her head to clear it.

"Your lunch, you haven't touched it." Taylor said slowly.

"Oh, uh, I'm just…not hungry." Gabriella sighed.

"Are you sick?" Taylor leaned over and felt Gabriella's forehead. Gabriella leaned back to get away from Taylor's hand.

I'm sick inside. "I'm just not feeling myself today, that's all." Gabriella chanced a glance at Troy who met her eyes and both blushed.

"Come on, Troy, you know I can throw farther than you!" Chad taunted.

Troy suddenly looked disinterested, "No you can't. Uh, I'll be right back…I just remembered I had to give something to Darbus." He muttered, pushing away from the table and shooting Gabriella a quick, meaningful look.

Gabriella watched Troy walk out of the cafeteria while everyone else began talking and eating again.

Gabriella waited a few minutes then pushed back as well, "I'm gonna get some Advil, I'll see you later." She told Taylor then also walked out of the cafeteria.

Taylor watched her friend worriedly then shrugged and went back to rolling her eyes at Chad.

Troy was waiting for Gabriella at the end of the hallway, leaning against a row of lockers casually. Gabriella hesitated then walked up to him and crossed her arm, staring over Troy's head.

"Gabriella…" He started.

Just like last night… "No, Troy." Gabriella cut him off, surprising herself as much as she surprised Troy. "Let me talk: You don't get to get away with what you did. You kissed me last night even though you are dating Sharpay!" Gabriella dropped her voice down low so no one would over hear them.

"Gabriella…" Troy tried again but Gabriella glared at him and he shut up.

"You knew it was wrong! You're the one at fault!"

"Gabriella!" Troy almost yelled then they both looked around to make sure no one had heard him. "I don't see why you're freaking out about this, I mean, it's not that big a deal…right?"

"Not that big a deal?!" Gabriella almost shouted then dropped her voice, "Not that big a deal?! Are you crazy?! You cheated on your girlfriend last night and it's 'not that big a deal?!'" She whispered fiercely at him.

She shook her head in disgust and shoved his shoulders so he slammed backwards into the lockers, "You're despicable." She hissed then spun on her heel and stormed away, wiping angry tears from her eyes.

Now I'm stuck with this feeling in the pit of my soul
guess I should of had a little self control
I knew that it was wrong, I admit it
I wish there was a way that I could make it alright
I really wanna tell you that I put up a fight
but that would be a lie

Gabriella threw herself down on the steps of the stage and sobbed into her hands.

What did I ever see in him?! He's the most shallow, most unbelievable, most, ugh, frustrating boy I've ever met! I can't believe I actually liked him! She ranted in her head, trying to stifle her tears.

You know you liked it… Her subconscious teased meanly.

Gabriella wiped at her face furiously, "I did not like it!" She lied out loud.

How could I do this to Sharpay? No one deserves this…Even if she is a bitch…Why is she even with him?! Gabriella got up and began pacing back and forth in front of the stage.

Maybe I could explain everything that happened to her so she realizes that he started it! But then she'd want to know how come I didn't push him away…I guess I can't lie my way out of this.

And now I'm sick inside
yeah, it makes me wanna cry
I'm so sorry about last night
yeah, it happened so fast
I wanted it to last
in the moment it felt so right
but now I'm sick inside

The bell rang. Gabriella didn't move. She stayed in the auditorium through the next period and the one after that. No one came in to check on her, no one cared that she, Gabriella Montez, 'freaky math girl,' was skipping class.

Gabriella spent the two free periods thinking about everything that had happened, trying to tighten the reigns on her guilt.

She couldn't help but feel terrible about what happened; she never wanted to be 'the other woman;' she never wanted to cause someone pain; she never wanted to put herself through this torture of trying to undo something that couldn't be erased.

Maybe she was just too empathetic, maybe she was too soft but Gabriella couldn't ease the raging cramp she had deep inside. This was something Midol couldn't solve. Only forgiveness could free her from this punishment and she didn't see that happening anytime soon.

Now I'm sick inside
yeah, it makes me wanna cry
in the moment it felt so right

Gabriella heard students moving around outside and she could pick up random snippets of conversation.

"I heard he slept with her!"

"No way!"

Gabriella's ears perked up, were people talking about her?

"Wanna go out with me tonight?"

"Ew, you're gross."

Eh, maybe not.

"Hey Sharpay, can I talk to you?" Gabriella froze again; it was Troy's voice!

"Sure Troy, what's up?" Sharpay simpered.

Gabriella began chewing her lip, her tainted lips, as Troy pulled Sharpay aside. Troy and Sharpay were drowned out by passing students and Gabriella inwardly cursed them for being so loud.

She was waiting for the bomb to drop, for the moment of truth to be revealed, feeling the calmness before the storm.

"YOU WHAT?!" Everyone in the school heard Sharpay scream in anguish and the unmistakable sound of Troy's facing being slapped.

Gabriella stepped closer to the stage as the auditorium door slammed open and Sharpay strutted in, "YOU!" Her voice echoed.

Gabriella took a deep breath then turned to face the blonde beauty's wrath.

I'm just a girl who
kissed a boy who
is in love with you

The song is Sick Inside by Hope Partlow. This isn't my best but I've never been very good with song fics. I might make this more than a oneshot but I haven't decided yet. Please review, I need help decided if I should continue or not. Thanks for reading, XOXO!
