A/N: Hello, this is the first story I published and completed on here. Hope you enjoy!

Ariana doesn't like the idea of moving in with her stepdad, Robert. Her mom, Joan thinks it is best to move in before they get married.

The little brunette misses her dad, and doesn't know the reason why her parents divorced. It happened when she was young and her mom would never tell her.

After Joan parked in front of the drive way they both got out of the car, observing the house.

It's painted in pastel blue and the window sills were white. The roof went upwards in a slant in both directions.

"Pretty nice house huh?" Joan smiled.

"Not as nice as our old house." Ariana muttered.

Joan opened the trunk and grabbed some bags. Ariana helped her and they both walked onto the porch.

Robert opened the door and saw them, struggling to carry the bags.

"Let me help with that." Robert took the bags out of their hands and went inside.

"Thanks honey." Joan said as her and Ariana went in after him.

"Harry!" Robert called his son.

A boy with curly brown hair came downstairs.

"Yes?" He asked.

"I need you to help Ariana with these bags and show her, her room." Robert told him, pointing at the bags.

"Ok." Harry picked up Ariana's bags and went upstairs.

Ariana followed his trail which led to her new room where there's already a bed and a wardrobe for her.

"Your room is next to mines. Just don't bother me and there won't be a problem." He dropped her bags on the floor and left the room.

Ariana sighed as she sat on the bed. Her eyes wondered around the room. The dull grey walls made her cringed. She reminded herself to paint them pink later. Her eyes can't stand looking at the wall so she looked out the window.

A dark haired boy is walking towards the house. He caught her staring and she quickly backed away from the window.

The boy rang the doorbell and Harry opened the door.

"Hey Zayn, what are you doing here?" Harry asked as he stepped aside to let his friend in.
"What do you mean? I always come here." Zayn chuckled.

"Yeah, but I told you my stepmom and stepsister are moving in today." Harry reminded him.

"Oh yeah, I forgot." Zayn scratched the back of his head. "Well since I'm here aren't you going to introduce me to them?"

"No." The curly haired boy frowned.

"Why not?"

"Because I barely know them."

"Harry, they are going to be apart of your family. You have to get to know them sometime soon."

"They will never be apart of my family!"

Ariana overheard them from her room. She agreed with the lad. They barely know each other to become family. It's like moving in with complete strangers.

She began to unpack and she found her diary. A smile appeared on her face as she flip through the pages, reading old memories. She giggled when she read an entry about her first crush, Justin. She put her diary on the nightstand by her bed and continued to unpack.

Zayn followed Harry to his room.

"So when is the wedding?" He asked, sitting on Harry's bed.

"Next month." Harry sat next to Zayn and handed him an Xbox controller.

"Am I invited?"

"Of course, you're my best mate."

"I never really been to a wedding before. What am I suppose to wear?"

"Something nice."

"Am I suppose to-"

"The wedding isn't until next month, so you don't have to worry about it now."

"Alright. I need to use the bathroom so pause the game." Zayn got up from the bed.

"Hurry up!" Harry playfully shouted as his friend left the room.

Zayn stopped when he saw Ariana walking towards the stairs.

"Hey, you must be Harry's stepsister. I'm Zayn, his friend." He introduced himself.

"Oh um...I'm Ariana." Ariana said, awkwardly.

She observed the boy, and noticed it's the same boy she saw outside. He has dark hair, hazel brown eyes, cheekbones, a chiseled jaw, olive toned skin, and his right arm is covered in tattoos.

"You like what you see?" He smirked which made Ariana blushed.

"Don't worry you'll see me around a lot." He winked before heading to the bathroom.

Ariana smiled to herself as she went downstairs to look for something to fill her empty stomach, but stopped when she heard her mom in the kitchen talking to Robert.

"I was thinking Harry and Ariana need to bond more, before the wedding. Harry is still not over about...you know?" Robert told Joan.

Ariana raised an eyebrow, wondering what Harry is still not over about.

"How come you never told me that you had a cute stepsister?" Zayn walked into Harry's room.

"You saw her?" Harry furrowed his eyebrows.

"Yeah, I was just talking to her a couple minutes ago." Zayn sat next to the curly haired boy.

"I don't want you to talk to her again ok? She isn't apart of my family."

"I know you're still not over about-"

"Don't bring that up!" Harry raised his voice, cutting Zayn off.

"Ok sorry..." Zayn frowned, feeling bad.

Ariana groaned when she heard the sound of the annoying alarm clock on the nightstand. Her eyes were still shut as she managed to extract her right arm from the covers. She felt around the alarm clock on the nightstand and pressed the off button. She opened her eyes slowly and pulled the covers off of her. She sleepily stumble over to her wardrobe, grabbing her white towel that was folded up on the top shelf, before heading to the bathroom.

Harry sleepily walked over to the bathroom. When he twist the doorknob, it was locked.

"Who's in here?" He knocked on the door, but then he heard the shower running.

He groaned and crossed his arms. He tapped his foot, waiting impatiently. After 40 minutes Ariana opened the door, all dressed up and ready for school.

"What the hell were you doing in there?!" He snapped.

"I was getting ready for school." She rolled her eyes, walking pass him.

He shook his head and went in the bathroom.

Ariana grabbed her backpack from her room and went to the kitchen. The table has two plates of pancakes that's already made for her and Harry. She took a seat in front of the plate and began to eat.

"Morning Ariana." Robert smiled, before taking a sip of his coffee.

"Morning." She mumbled with a mouthful of pancakes.

"Harry will be driving you to school, and show you around."

"I will be what?" Harry entered the kitchen.

"You will drive her to school, and show her around." Robert repeated himself.

Harry groaned, taking a seat across from Ariana. He glared at her and she just swallowed her food making a big gulp.

"I'm gonna go to work. I'll see you both at dinner." Robert grabbed his keys and left the house.

"We should head to school." Harry got up from his seat.

"I thought school starts in 20 minutes." Ariana gave him a confused look.

"I know, but I need to show you around." He walk towards the door. "So are you coming or what?"

Ariana got up and followed him out the house. They both got in his car.

"I need to pick up my friend, Zayn first." He said as he put on his seatbelt.

Ariana nodded, putting on her seatbelt as well. Harry put the keys in the ignition and started to drive his way to Zayn's house which isn't far.

He texted Zayn that he's here and after a couple of seconds Zayn came outside. He got in the back seat since Ariana is sitting in the front next to Harry.

"Hey, so why are we going to school early?" He asked.

"I need to show Ariana around." Harry told his friend.

After a couple of minutes they arrived at the school. He parked in the school's parking lot and they all got out of the car. Harry and Zayn entered the school and Ariana followed them. She gained some stares from other students.

"Selena, can I borrow your notes from History?" Tori asked her friend who was busy staring at Harry, Zayn, and Ariana.

"Who's the new chick and why is she with Harry?" Selena asked, ignoring what Tori said.

"Isn't that suppose to be his stepsister?"

"Oh yeah. We should be her friends since she's new."

"You just want to be her friend so you can get closer to Harry."

"That is not true!"

Their friend, Demi walked over to the two girls.

"Hey." She smiled at them.

"Hey Demi." Tori smiled back.

Demi noticed that Selena didn't respond.

"What's up with her?" She pointed at Selena who is still staring at Harry.

"Harry." Tori told her.

"Ah." Demi looked over at Harry. "Anyways I keep getting notes from my secret admire. I still don't know who it is."

She handed Tori the note.

"Maybe it's a joke." Tori read through the note.

"Maybe." Demi shrugged.

Tori saw, Niall, Liam, and Louis walking by.

"Oh my gosh Niall is coming! How do I look?" She asked, pointing at her face.

"You look fine." Demi said.

Tori looked over at the boys and gave Niall a smile. "Hi Niall!"

He just gave her a nod.

"He gave me a nod." Tori frowned.

"At least he gave you something." Demi laughed.

Ariana, Harry, and Zayn are at the office.

"This is Ariana Grande, my stepsister." Harry said to the lady who's sitting behind the desk.

"Ah yes, we were expecting her." The lady nodded. "Here is your locker number, schedule, and the student handbook."

She handed Ariana the stuff. Ariana thanked her before they left the room.

"We have first period history together." Zayn said, looking at her schedule, and she smiled.

Harry and Zayn gave Ariana a quick tour around the school before class starts. Now she knows where her classes are.

"I'll see you guys at lunch." Harry said to them as he walked to his class.

"So what do you think about the school?" Zayn asked Ariana as they both walked to class together.

"It's a lot bigger than my old school." She said and he chuckled.

They both entered the room and Ariana stopped when she saw a familiar face.

"Justin?"
