Natsu didn't understand at first why Juvia had wanted a piano when they'd first moved into their apartment. He could've sworn the only time it made noise was when he was tapping on it out of boredom, and that other than that it was mostly to fit her aesthetic.
That was until he walked in her and Gajeel's singing lessons. Now, one would think Gajeel giving Juvia voice lessons would be counter productive, but Natsu could tell you otherwise.
"You got it all wrong, Blue!" Gajeel laughed, tapping the keys Natsu presumed were at the lower end of the piano. "Try again."
"Do, Re, Mi, Fa, So, La, Ti, Do~!" she sung, a lot lower than usual.
"There you go." he tapped the higher keys now. "Now match this melody."
"Do, Re, Mi, Fa, So, La, Ti, Do~!" she sung a little higher.
This continues until they were on the higher end of the piano.
"Good." Gajeel said. "Let's try that song again."
From his hiding spot in the kitchen, Natsu peaked at Gajeel and Juvia. They were wearing matching jumpers, which he would never say pissed him off more than he wanted to admit. Gajeel was flipping through a notebook as Juvia looked out the window.
"Just cause you want him home doesn't mean he'll come faster." Gajeel smirked at him.
"Maybe, but Juvia just likes to think about him." she grinned at Gajeel.
"You two make me sick." he laughed, positioning the notebook on the stand.
"Like you don't miss Levy when she's away." she bumped into his shoulder. "Isn't this song for her?"
"Shut up, Blue!" Gajeel chuckled in embarrassment. "You ready?"
"Yes sir." she laughed.
Gajeel started to play a song, and Natsu couldn't help but lean further out of the kitchen as his girlfriend started to sing.
"No New Year's Day to celebrate,
No chocolate covered candy hearts to give away.
No first of spring, no song to sing,
In fact here's just another ordinary day.
No April rain,
No flowers bloom,
No wedding Saturday within the month of June.
But what it is, is something true,
Made up of these three words that I must say to you;
I just called to say I love you,
I just called to say how much I care.
I just called to say I love you,
And I mean it from the bottom of my heart.
No summer's high,
No warm July.
No harvest moon to light one tender August night.
No autumn breeze,
No falling leaves.
Not even time for birds to fly to southern skies.
No Libra sun,
No Halloween.
No giving thanks to all the Christmas joy you bring.
But what it is, though old so new,
To fill your heart like no three words could ever do.
I just called to say I love you,
I just called to say how much I care, I do.
I just called to say I love you,
And I mean it from the bottom of my heart.
I just called to say I love you,
I just called to say how much I care, I do.
I just called to say I love you,
And I mean it from the bottom of my heart, of my heart, of my heart!"*
Gajeel hit the last notes on the piano before they both broke out in a fit of giggles as Juvia clapped giddily.
"You nailed that one, Juvia!" Gajeel said as he stood up and offered her a hand.
"We did! Levy's going to love the song Gajeel!" she spun herself with his hand. "Before he leaves, does Gajeel want some hot chocolate? Juvia has some from the last lesson still."
"That sounds great, Blue; sure, I'd love some!"
Natsu panicked, trying to hide better before they walked in on him and got beat up, because while he could take on Gajeel, he would never hurt Juvia, except for that one sparring match that he swore on his life was an accident! (It was.)
Of course, Natsu's stealth skills betrayed him, for just as he stood up, he knocked over the sugar jar, which doused him in sugar before smashing on the ground.
Gajeel and Juvia stared at him, Gajeel looking a little annoyed and pissed. He still looked very intimidating, even if his face was flushed from embarrassment, knowing full well Natsu had heard the song intended for his girlfriend.
Juvia on the other hand seemed very happy to see him, but contained herself rather well. She leaned on the frame with her arms crossed. She smirked at him. "How sweet of Natsu to drop by."
Gajeel couldn't contain his laughter, and unfortunately for him the cough didn't save him.
Natsu took this as a sign neither was actually that mad at him and proceed to clamour his girlfriend about how much better she'd gotten at signing, who faked to be offended because 'Was Juvia not good enough before!?'. Now Gajeel watched as he chased her around the kitchen trying to kiss her, even though she kept telling him to stay still since he was getting sugar flakes everywhere.
He chuckled to himself. There was always either the lovey dovey couple vibe or the super dumb couple vibe in the Dragneel-Lockser house.
He made his way out of the house without getting noticed, since they were too busy peck-kissing each other to death. He left Juvia a note on the counter.
'Next time, the lesson is at my house; make sure your voice is not hoarse from yelling his name all night ;P ~ love and be safe, Gajeel'

This is what the song would sound if played on piano, and this (V) is the original version.
