If anyone still remembers, I did promise another Percabeth story so here it is. And also I decided not to delete my story Missing You since a lot of you really liked it. And yes, this is a basic copy of the book Perfect Chemistry. I know I know it isn't original this way but I'm not too creative *shrugs*. Anyway, here's the basic summary:

In this story, Uppers and Lowers rarely get along. This story will be about what happens when Upper smart rich girl Annabeth becomes chemistry partners with Lower gang member Percy. So mostly it'll be Lukabeth *gags* Percabeth, some Gruniper, and a little bit of Tratie.

Disclaimer: Don't own any of the characters.

Annabeth

Everyone knows I'm smart. Maybe it's because it seems to run in the family. My mom is an architect. My dad is a history professor at NYU. I've been working hard to keep up my status as the smartest girl in school, every school: elementary, middle, and now high school.

Standing in front of my mirror, I straightened my outfit and double-checked my appearance, hoping everything will turn out right. First day of school meant seeing my boyfriend after spending the summer apart. Hopefully, not much has changed.

"Annabeth, come down," I heard my mom yell from the front of our apartment.

"Coming," I call back. After brushing my blond hair, I headed out of my room and down the hallway to the living room. My mom is standing by the couch, scanning my outfit with her analyzing grey eyes. I straighten my posture, hoping this time she'll approve this time. It may seem silly, being a sixteen year-old and still conscious of what my mother thinks, but everything in our family needs to be perfect for her.

"Good enough," Mom told me. It was always the same. I was only just good enough. Never above her expectations.

"Good morning, Mom," i say to her before heading to the kitchen.

"I brought you your favorite muffin. A good breakfast leads to a healthier mind."

"Thanks, Mom."

As I headed to the kitchen, my younger twin brothers, Bobby and Matthew, burst through the living room.

"Boys, no running in the apartment," Mom warned, but, as usual, they ignored her. They ran past me and ran straight to the kitchen. I followed them, hoping I could grab my mufffin and leave just to eat in peace. As Bobby grabbed a Go-gurt, Matthew grabbed another and pointed it accusingly at his brother.

"Did you take my toy robot?" he demanded.

"No," Bobby answered but his voice quivered slightly. showing that he was lying.

"Give it back!" Matthew yelled. He opened his Go-gurt and squeezed it. Bobby ducked and the yogurt hit me instead, staining my white blouse.

"Oops," Matthew muttered. "Sorry, Annabeth."

"Matthew!" Mom exclaimed.

"Mom, it's ok," I assured her. "It was just an accident."

"Well, the fact that they have ADHD isn't an accident."

I sighed as I headed back to my room. Since the boys have ADHD, it made it harder for them to perform better in school. It's been my responsibility to keep the family pride and be "the genius" in my classes.

I looked at my watch to find that it was already ten minutes past seven. I needed to get out of the apartment soon or else my friend, Katie Gardner, will kill be for bringing both of us late to school. I grabbed a green scarf and left my room. Before I left the apartment, I grabbed the bag with my muffin in it.

"Love the scarf," I heard her call out. Thank God she liked something for once.

I left the building and headed to the garage where my BMW was parked. Inside, I bit into my muffin, finding that it wasn't blueberry. It was banana nut and yet it reminded me of myself; perfect on the outside, soft and crumbling on the inside.

Percy

"Percy, wake up!" someone yelled. As I began to wake up, I recognized the voice to be my fourteen year old adopted brother, Nico.

"What do you want, Nico?" I groaned.

"Sally told me to wake you up," Nico said, referring to my mother. I knew it was the first day of school, but all I wanted was to keep on sleeping. I tried covering my head with my pillow.

"Perseus!" I heard my mom yell. "Wake up now!"

I groaned again as I forced myself to get out of bed. I headed to the bathroom and looked at myself. My black hair was sticking up everywhere and my sea green eyes still looked bloodshot. I hopped into the shower, letting the cool water wake me up.

Once I got out, I looked across to see Nico in my room holding my black and blue gang bandana. I swear I get frustrated with this kid every time he tries to follow in my footsteps. I walked over to him and snatched my bandanna away from him.

"Nico, I told you already I don't want you going through my stuff," I said to him. Nico just shrugged his shoulders, obviously not caring about whatever shit I tell him.

"I like black," he simply responded. It was true, he did wear a lot of black ever since his sister died. But that didn't give him any excuse to take my stuff or worse join the Half-Bloods like me and my dad did. If it was my choice, I would've stayed away from the Half-Bloods, but our family needed the money.

"Listen, Nico," I warned him. "Being me is nothing you want to experience. It don't matter how everyone treats me these days. Being in a gang isn't something you want to do."

With those final words, I let him go, knowing he'd be too stubborn to listen. Oh well, I warned him. But I still loved the kid as much as I love my mom.

We headed to the kitchen as Mom was setting down plates of pancakes. As much as I love Mom's cooking, I needed to get to school fast. But before I could go past the door, Mom called out to me.

"Perseus, where are you going?" she asked.

"Mom, I got to get to school," I told her.

"You've got time, Perseus," Mom pushed me towards the table. "This morning, we're going to eat together like a family. And no buts."

Looking across at Nico, I could tell he was into this as much as I was. Sighing, I sat down and tried to eat the waffles Mom had cooked.

"Why can't you just call me Percy?" I asked her.

"What's wrong your given name?" she asked back.

I tensed as she asked that question. I didn't want to tell her that I was bothered by the fact that it was my father who named me Perseus. The father that left our family, left the son that was left the idol of the father in the family.

"Percy wants to be just like a gang member," Nico replied for me. "And he's really succeedin' too. Pretendin' to be someone he's not."

"Nico!" Mom reprimanded.

My anger took over and I got out of my seat, walking straight to him. He got out of his own seat and and close the distance between us. He knew I could beat him up and yet h found the guts to confront me. This ego of his would one day get him in a hell lot of trouble. Hopefully I cold keep him away from that happening.

"Now listen, Nico," I warned him. "You have no idea what the hell I deal with everyday. Bein' a gang member isn't everythin'. And I hope that you'll learn better than to follow my footsteps. You could be a lot better than me."

"Maybe I don't want to be any better than you," he responded. "People are goin' to think that I am like you. No point in makin' them think different."

"No, Nico," I said to him. "You know you could do better than me."

Looking back at my mom, I noticed her tears and tried to give her a hug for comfort. Kissing her goodbye, I grabbed my leather jacket and headed out the door. Two guys wearing the same black bandannas made a clawed hand over their hearts and made a shoving movement towards me. I repeated the gesture back at them before I sat in my motorcycle. They wanted a tough gang member, they got one. Sometimes I play the part so well that I even surprise myself.

"Percy, wait up," a female voice called behind me. I turned to see Rachel Elizabeth Dare, my ex-girlfriend.

"Hey, Rachel," I mumbled.

"Could you give me a ride?" she asked. Before, I would've done anything for her until I found her with some other guy in his car over the summer.

"Please, Percy. I won't bite," he asked again, batting her long lashes at me. Rachel was a Half-Blood too and Half-Bloods always help each other. The flirting was totally unnecessary.

"Hop on," I told her.

She hops on and puts her hands on my waist, deliberately pressing her body against my back. Her flirting wasn't going to work on me. I'm not likely to forget the past. This year, I was determined to focus on my senior year. I knew it was going to be difficult, because after high school, my future was a big blur.
