A/n: Wattpad was being hard on me so I found a cover of this song. It's one of my faves from MITAM! :)
Song: I Want To Write You A Song by One Direction

"Ready for surprise 4.2?" He asks you and you raise an eyebrow. "Surprise 4.2?" "Yeah! The cake was 4.1! This is 4.2!" He says and grabs a small box wrapped in wrapping paper with a bow. You smile and nod as he gives you the box.

You carefully unwrap the paper and it indeed was a box. You opened it up and gasped when you saw what it was. "C-Cole..A-a Locket? Oh my god.." You say in shock as you take it out of the box and look at it closer. It was a silver split locket heart with a silver chain.

Cole smiles, "Open it up." You do as told and open up the locket. Inside was a picture Cole that you took on one of the dates with you. It was beautiful. "Wait, this looks like half a heart...so where's the other?"
You asked and Cole comes closer to you and shows you the other half around his neck.

Cole opens it up and it's a picture of you that he took on the same day you took a picture of him! Cole smiles and closes it back up. "I'm your other half. But! There's something else you should know about these lockets." He says.

Cole gets behind you and puts your locket around your neck before sitting back in front of you. "What is it?" You ask looking at. "This!" Cole says then connects his locket with yours and it becomes a whole heart!

"Aww Cole!! This is the best!!" You say and he disconnects both hearts. "Yup! But I'm not done yet! Time for present 4.3 so get comfortable!" He says and you chuckle and grab a pillow and hug it.

Cole grabs the guitar and plucks a couple strings to make sure it's tuned. Once it's tuned Cole looked at you with a smile and began strumming to a song.

"I want to write you a song,
One that's beautiful as you are sweet,
In just a hint of pain,
For the feeling that I get when you are gone,
I want to write you a song." He sings and you sigh dreamily.

"I want to lend you my coat,
One that's as soft as your cheek.
So when the world is cold,
You'll have a hiding place you can go,
I want to lend you my coat." You scoot closer to Cole.

"Everything I need I get from you.
Givin' back is all I wanna do." You watch his fingering on the guitar and listen as he sings the lyrics.

"I want to build you a boat,
One that's strong as you are free.
So any time you think that your heart is gonna sink,
You know it won't.
I want to build you a boat."

"Everything I need I get from you
Givin' back is all I wanna do." As Cole strums the instrumental part you lean your head on his shoulder. Cole was making today a perfect day for you and you couldn't be more happier.

"Everything I need I get from you
Givin' back is all I wanna do.
I want to write you a song,
One to make your heart remember me.
So any time I'm gone,
You can listen to my voice and sing along.
I want to write you a song,
I want to write you a song." Cole finished singing and you gave him a hug. "That was beautiful." You say to him.

Cole puts down his guitar and you let go. "Happy birthday cupcake. I love you." He says with a smile and you smile back. "I love you too but, can I say thank you now?" You ask and he chuckles and thinks for a minute. "Yes."

"Thank you for everything you've done for me today Cole. You seriously took birthday to the next level! Haha but thank you, you remembered and you were sweet so yeah, thanks." You tell him and slowly lean in.

Cole connects his lips to yours in a soft sweet kiss. You two then let go but both of your lockets connected again! You two chuckle and disconnect the hearts. You then lean your head on Cole's shoulder as you two look at the sunset.
