This is the first songfic/oneshot I've written, so get ready for feels like no other.

It was December 25th, 2017, AKA: the day Bearquarter's Toy Story 3 was about to premiere, and normally, Christmas is a time to feel good. But for Danny Phantom, the world's greatest hero. It's another story. Danny actually hates the holiday season because every year, his parents always argue about the existence of Santa Claus, and these arguments have always led to Danny suffering traumatic childhood memories. Such as the family dog urinating on him when he was just a baby, or a ghost possessing the Christmas turkey. But this Christmas has been hectic for the poor ghost child. The whole 2017 as a matter of fact, because he was planning to reunite with the one he's been close to since pre-school, the Loudest Loud and Toon City, Oklahoma's rock Goddess, Luna Loud. But because of the Loud kids' meddling in Dexter's lab, there's trillions of Loud girls, which means Millions of Luna Loud Since January, he's been looking for the Real Luna and has been trying to find a way to break the truth the easy way.

Danny sighs as he exits the room, and heads off to the theater, via flying there as Danny Phantom, Luna and Danny have been very close with each other. Since the day they've met, they used to be closer than Sam and Tucker.

When somebody loved me
Everything was beautiful

When they were kids, Luna and Danny would spend every day after school playing in the park or even at their houses, enjoying each other's company every single moment of the day. From playing Backyard Baseball games to playing in the Jungle Gym, they've grown close every day in their childhood. even Sam and Tucker and Luna's friends were jealous of Danny's friendship with Luna. Even Luan started to feel left out.
Every hour spent together
Lives within my heart

And when she was sad

And whenever Luna was being bullied or getting hurt, Danny was always there to help Luna feel better after a hard and stressful day at school.
I was there to dry her tears
And when was happy so was I

Lynn Sr. didn't trust Danny at first, but eventually, the Louds warmed up to Danny and treated him like he was Luna's husband.
When she loved me

Through the summer and the fall

But the friendship went to another level when they saw a movie together while hanging out with their classmates. They shared a kiss with each other. And thanks to Terrence, the school's biggest douchebag, ratting out the kiss, their friendship was rumored to be more than friends.
We had each other that was all
Just she and I together

But even though Danny and Luna didn't want to admit it, they secretly thought they could have more a relationship with each other like a couple, but they decided to stay friends for the time being.
Like it was meant to be

And when she was lonely
I was there to comfort her
And I knew that she loved me

To Danny, it seemed like his friendship would last forever with Luna...

Sadly, that was not meant to be as things have changed since Danny's 10th birthday. One day during his 4th grade year, Danny's parents were constructing a ghost portal to prove that there is some proof of the supernatural, however, while the parents were close to being completed with working on the portal, he didn't anticipate on his friends helping him. While in his laboratory, Danny had an accident involving the newly built "Fenton Portal", causing his molecular structure to infuse with ectoplasm.

As a result, Danny Fenton became a half-human, half-ghost hybrid; he styles himself as a new persona as Danny Phantom, an extraordinary spectral superhero with a ghostly array of other-worldly powers; able to shift between the forms his human-half and his ghost-half at will, coming into a number of various supernatural/paranormal extraordinary abilities. As Danny impressed and won over people as the world's 2nd greatest teen hero (Next to Spider-Man), Luna became distracted by one thing: Her path to becoming a rock star.

Luna's passion for rock music developed when she was in the 5th grade. She was still trying to find her own calling at the time. She went to her first concert, and witnessed the lead performer, Mick Swagger, on stage singing, and calling out to her. She took the stage with Mick, and suddenly found out that the world of rock was where she was meant to be and that it was her destiny. Since that day, she has viewed Mick as her hero, because he gave her the inspiration to rock on.

But at a cost...

So the years went by
I stayed the same

As Danny protected the world as a hero, as a normal human, he started to notice how busy Luna was becoming with Rock n' Roll. It got to that point where Luna actually forgot about having Danny as a best friend. She became busy with Rock and roll and being with her sisters and friends that she didn't even text and/or call Danny anymore.
But she began to drift away
I was left alone

Even with friends like Sam and Tucker, they weren't enough to fill the empty hole in Danny's broken heart. Since then, Danny could only clutch the framed picture of the one happy and loving memory of his time with Luna was the day they kissed when they saw that movie with the 3rd graders that September morning when they were 8 year old kids.

Still I waited for the day
When she'd say I will always love you

For a while, it seems as if Luna would never see or hear from Danny Phantom again...

Lonely and forgotten
Never thought she'd look my way

That was until the Rivalry Football Game between Toon City High School and MacFarleneville High School in Danny's freshman year that he and the other students went to at Toon City College and Danny crossed paths with Luna once again at the concession stand during Halftime, and so far it was a happy reunion.
And she smiled at me and held me
Just like she use to do
Like she loved me
When she loved me

Toon City won a nail biter, and hanging out with Luna made it the best night in Danny's life. It was the happiest he's ever been. But it was a bittersweet reunion as Luna decided to remain friends with Danny Fenton.

When somebody loved me
Everything was beautiful

While Danny didn't want to admit it, he felt heart broken a little bit at the fact that they would stay friends when Danny wanted to be more than friends.
Every hour spent together
Lives within my heart
When she loved me
