"Guys! I need your help with something!" Harry shouted excitedly when he arrived at the teacher's longue before Louis on Monday morning. Louis had gone home for a change of clothes after waking up at Harry's flat. He should probably give him a drawer at his place for a change of clothes. He already had his own toothbrush in the bathroom.

"What do you need help with?" Liam asked.

"I finished the song! Will you sing it with me?" Harry asked. He was too nervous to sing it by himself.

"Really? You should do it alone. This is your moment." Zayn answered.

"I'm too nervous! I need you to back me up." Harry pouted.

"Of course we will, right guys?" Niall said and looked around at the others.

"Sure. Can we hear the song?" Liam asked.

"We all have a break at ten, right? Just come to the music room. I'll play it for you." Harry smiled relieved.

Louis came rushing into the teacher's lounge and they stopped talking. They headed to their first classes a couple of minutes later.

The boys came into the music room at ten. Harry knew that Louis was busy teaching a class so this was the perfect opportunity to play them the song. He went to get a guitar and took a deep breath before he began to sing. When he was done Niall, Liam and Zayn clapped their hands.

"Great song Harry!" Liam complimented.

"Beautiful!" Zayn smiled.

"Louis is so gonna cry when he hears it." Niall grinned.

"So you think he'll like it?" Harry asked nervously.

"He'll love it! Oh God, I need to start dating. I feel so single all of a sudden." Niall grunted.

"I hear you." Liam laughed.

"Yep." Zayn smirked.

"You'll find someone soon, I'm sure of it." Harry tried to comfort them.

"Maybe. So, how do you want to divide the song between us?" Liam asked and Harry gave them all a copy of the lyrics and what part they would sing. They rehearsed it once and it sounded great.

At lunch, he asked Louis to meet him in the auditorium after work and Louis immediately agreed. He was curious about it, especially after Harry refused to tell him why and the three other lads were giggling exhilarated.

As soon as the day was over he hurried over to the auditorium just to find all four boys sitting at the edge of the stage. Niall had a guitar in his lap.

"Okay, I'm here. What's going on?"

"Please take a seat." Harry smiled.

Louis looked confused but he sat down on the front row in front of them. Harry cleared his voice.

"So....ehm, I wrote a song for you and I know that's really cheesy and all but I would like to play it for you. The guys are helping me out because I'm really fucking nervous." He said with a snort in the end.

Louis's mouth fell open.

"You wrote me a song?"

"Yeah, just bear with me, okay?" Harry chuckled.

"I love it already." Louis smiled.

"You haven't even heard it yet." Harry giggled and rolled his eyes at him.

"It doesn't matter. It will be amazing. Thank you, baby." Louis said softly and Harry blushed from the use of the pet name. The three others looked amused. He nodded in Nialls direction to tell him to begin playing and took a deep breath. Niall played the intro and Harry looked down on the floor while he started to sing.

I got a heart, and I got a soul

Believe me, I will use them both

We made a start

Be it a false one, I know

Baby, I don't want to feel alone

Harry glanced at Louis. He looked emotional, staring at him with glossy eyes. Zayn took over and sang the next part.

So kiss me where I lay down

My hands pressed to your cheeks

A long way from the playground

Harry found the courage to look directly at Louis when he continued with the chorus.

I have loved you since we were 18

Long before we both thought the same thing

To be loved and to be in love

All I can do is say that these arms

Are made for holding you, oh-oh

I wanna love like you made me feel

When we were 18

Louis's eyes didn't leave him and he seemed to listen to every word he sang. Niall took over.

We took a chance

They all turned their heads and smiled at Niall when he sang chonce instead of chance. English teacher, right? Louis let out a short laugh. Niall continued, not paying them attention.

God knows we tried

Yet all along, I knew we'd be fine

Liam was next in line.

So pour me a drink, oh love

And let's split the night wide open

And we'll see everything we can

Living love in slow motion, motion, motion

Zayn sang the pre-chorus once again.

So kiss me where I lay down

My hands pressed to your cheeks

A long way from the playground

They all sang the chorus together and Harry smiled when he saw that Louis sang along as well.

I have loved you since we were 18

Long before we both thought the same thing

To be loved and to be in love

And all I can do is say that these arms

Are made for holding you, oh-oh-oh

And I wanna love like you made me feel

Harry sang by himself.

When we were 18

Niall took over.

When we were 18

Oh, Lord, when we were 18

Zayn sang the pre-chorus for a third time.

Kiss me where I lay down

My hands pressed to your cheeks

A long way from the playground

Harry was just about to sing the chorus when he heard Louis's angelic voice sing his words back to him.

I have loved you since we were 18

Long before we both thought the same thing

Harry got a little teary-eyed and sang the next line with Louis.

To be loved and to be in love

They all sang the chorus again.

And all I can do is say that these arms

Are made for holding you

And I wanna love like you made me feel

When we were 18

I wanna love like you made me feel

When we were 18

I wanna love like you made me feel

Harry finished the song by himself.

When we were 18

Niall, Liam, and Zayn cheered and Harry looked at Louis, waiting for his reaction. He didn't have to wait long. Louis got up and threw himself at him, making Harry fall to his back. Louis kissed him passionately and the boys' wolf-whistled, but he didn't hear them. Louis broke the kiss and looked down at him with teary eyes.

"I loved the song and I love you, Harry."

"I love you too." Harry smiled.

It was the beginning of something great.

The End
