Hey this is just a cute idea that I thought of while listening to some music. Mostly just Jace/Clary cuteness. I do NOT own Mortal Instruments or any of its characters. I also do not own any rights to the songs in this story. Please read and review!

Jace threw his pen down, completely aggravated. How hard can it be? Clary's 18th birthday was in four days, and he wanted to write her song. He had learned guitar in the last two years, since they had returned from Idris after the battle, knowing how much she loved when he played music. She was always so happy when he played the piano for her; a smile never failing to escape her lips. He had decided to learn guitar also after being dragged by Clary to her house to watch one of those sappy love movies.

He honestly couldn't stand them but liked to watch them with her just to see her face. In this one particular movie the guy decided to play guitar and sing to his love interest. Completely over done if you ask me, was all Jace had been able to think. Clary had, of course, started to cry. Jace pulled her into his arms and sang in her ear, the well known lyrics to the song.

I could stay awake just to hear you breathing

Watch you smile while you are sleeping

While you're far way and dreaming

I could spend my life in this sweet surrender

I could stay lost in this moment forever

Where every moment I spend with you is a moment I treasure

Don't want to close my eyes

I don't want to fall asleep cause I'll miss you babe

And I don't want to miss a thing

Cause even when I dream of you

The sweetest dream will never do

I'd still miss you babe

And I don't want to miss a thing

Lying close to you, feeling your beating heart

And I'm wondering what you're dreaming

Wondering if it's me you're seeing

Then I kiss your eyes

And thank God we're in this moment

I just want to stay with you in this moment forever

Forever and ever

Don't want to close my eyes

I don't want to fall asleep cause I'll miss you babe

And I don't want to miss a thing

Cause even when I dream of you

The sweetest dream will never do

I'd still miss you babe

And I don't want to miss a thing

I don't want to miss one smile

I don't want to miss one kiss

I just want to be with you

Right her with you, just like this

I just want to hold you close

Feel your heart so close to mine

And just stay here in this moment

For all the rest of time, yeah, yeah, yeah

Don't want to close my eyes

I don't want to fall asleep cause I'll miss you babe

And I don't want to miss a thing

Cause even when I dream of you

The sweetest dream will never do

I'd still miss you babe

And I don't want to miss a thing

Don't want to close my eyes

I don't want to fall asleep cause I'll miss you babe

And I don't want to miss a thing

Cause even when I dream of you

The sweetest dream will never do

I'd still miss you babe

And I don't want to miss a thing

Don't want to close my eyes

I don't want to fall asleep

And I don't want to miss a thing

When the song was done she gasped and looked right up at him. Jace, you never told me you could sing. That was amazing."

Jace of course turned it into a joke. "All the more reason to love me."

Clary, surprisingly, ignored the sarcasm and kissed him. When she was done, she pulled back and agreed with his earlier comment. "You're right I love you more everyday."

That was when Jace had started to learn guitar. He had played for Clary many times and sang a countless number of her favorite songs, but this was different. He usually just composed music on his piano for her and it came naturally. But it was surprising to him just how difficult it was to add words to the music her had already written. How could her convey everything he felt for the beautiful, sweet girl that occupied his every thought in so few words? He wanted to be able to give her everything. After about five minutes of Jace just staring at the blank paper in front of him, hoping inspiration would come; he decided to give himself a break and grab some breakfast. It was only 9 o'clock but he had already been working on this song for three hours. He had nothing.

He walked down to the kitchen only to find a pouting Alec and Isabelle smiling victoriously. Jace suddenly curious asked, "What's up with you two?"

Alec was the first to respond. "Izz ate all of my food. It was in the fridge from yesterday when Magnus and I went to Taki's and now it's not here."

Isabelle gave her brother an annoyed expression. "It didn't have your name on it!"

"Yes it did!"

Isabelle's smile vanished. "Oh, well… I didn't see it .Too bad. I could make you guys something if you want."

"NO!" Alec and Jace shouted simultaneously. Isabelle made a face, and then changed the subject. "So, Jace, how are Clary's birthday plans going?"

Jace looked down at this, slightly embarrassed that something as simple as words had stopped him. "Good. I have everything set except for her song. The words… I just can't turn what I feel into lyrics." His phone buzzed signaling a text. It was Clary. "Speaking of, I got to go. I'm spending the day at Clary's. Call if you need me."

Jace was almost out of the kitchen when Isabelle shouted from behind him, "Oh Jace, Pandemonium tonight, ok? And bring Clary."

"Got it," he answered in return but her was barley listening. He was on his way to see Clary.

When Jace got to Clary's house, he bound up the stairs, taking them two at a time, and rang the doorbell. When the door opened and a smiling Clary answered the door, his breath was taken away. Clary, with her fiery crimson hair, emerald green eyes, and her sweet but stubborn personality. She was everything he could ever ask for.

He quickly closed the distance between them and hugged her. He whispered his hello in her ear and was rewarded with a shiver going down her spine. He cupped her face in his hands and kissed her. When they heard footsteps, they both released their hold on each other and stepped back. Jocelyn came into the living room and smiled. "Oh, Jace you're here! Good, I just finished making some muffins. You can come join us."

Jace smiled politely and said, "Thank you so much Mrs. Garroway." Jocelyn smiled at her newly given last name and led the way into the kitchen. After the three of them were done filling themselves with giant chocolate chip muffins, Jocelyn got a phone call. When she hung up, she looked down at the two teenagers who were talking to each other at the table. "Sorry, guys but I have to go to the studio. They need help setting up the pieces for the Gallery opening tonight. I'll be gone for a few hours, so…behave yourselves. Luke will be in the bookstore if you need anything. Love you, Clary. Goodbye Jace."

They both smiled and said their goodbyes. When they heard the front door shut, Jace turned to Clary and let out a small laugh. "You have a little chocolate right here…" He pressed his lips to hers and wrapped his arms around her small waist. When he pulled back she had the ghost of a smile on her lips. Playfully, she said, "Is it gone?"

Both of them, knowing that there had never been anything on her lips, laughed. Jace gave his signature smirk; that never failed to make Clary catch her breath; and said, "I don't think so." Whenever Jace kissed Clary he felt as if all of his nerves where on fire but at the same time the complete opposite. When he touched Clary it was if tiny electric shocks went through his body but he also wasn't aware of anything around him. It was Clary who pulled back first and said, "So… what do you want to do?"

Jace smiled and pulled her into his lap. He kissed her again trying to show her what he wanted to do. He would kiss her all day if he could. She pulled back and giggled. "Ok, Jace, you know what I meant. What do you want to do… other than that?"

They ended up in the living room, lying down on the couch; Clary snuggled up near Jace's chest. They stayed there almost all day just talking. This was Jace's favorite thing to do with Clary; well… besides kiss her. Ever word she spoke was like a gift for Jace. He could probably pick out her voice in a room full of people.

They could talk about everything, and they did. She spent almost an hour trying to explain public high school to him. She hadn't gone in a few years, having decided to be a full time Shadowhunter, but even after all this time of her trying to explain it, it still seemed pointless to him. While she laid there and tried to explain calculus to him he didn't have to feign interest in her like the average boyfriend would. No matter what she was talking about, he was interested.

By the time 6 o'clock came around, they both headed to the Institute to get ready to go to Pandemonium. Clary headed to Isabelle's room and Jace to his own. An hour later she came down to the elevator wearing a red halter dress that came to about mid thigh, just low enough to hide the sheath that held her seraph blade. Jace grinned mischievously when she walked down the stairs and he pulled her in for a passionate kiss. Alec grumbled something about getting a room and they all headed into the elevator. Jace was still worried about the song but tried to hide it from Clary. She could read him so easily by now that if he was even a little off, she could tell.

They all got to Pandemonium around 8 and Clary and Isabelle went into the crowd on the dance floor, trying to lure the demons to follow them into the storage room where the boys would soon follow to help out. Clary caught the interest of a demon and started to dance with him. When she whispered in his ear and started to drag him off the dance floor Jace couldn't help but feel worried and angry. The way that demon's hand kept slipping lower down Clary's back made Jace want to run across the club and kill him right now. Hold on. Clary's a professional. She's practically as good as you. Jace tried to think about all of the demons Clary had killed in the last couple of years but that still didn't ease the gut- wrenching nervousness that came every time Clary went out on her own. The door to the supply room shut and Jace knew that was his cue. It was time to kill some demons.

Thanks for reading. I hope to finish this up in the next chapter. Please review!
