A/N: Hi! This is my very first fic for Miraculous and my first fic on here in about five years... wow, lol! I have no idea where this is gonna go but I'm excited to explore and see. Also, the canon timeline of the show is a bit jumbled with things like Desperada (where Luka gets the snake miraculous for the first time) happening sooner alongside of Jagged being *spoiler* Luka's dad being known before he meets Marinette. That's it!

Chapter 1: Sharing

"Happiness comes from helping others, by being with others, and by sharing, even if it's only a smile."
― Zain Hashmi

Growing up, Luka had been used to the idea of sharing. Having a twin and living on a boat demanded it.

He had shared a room, a bathroom, a kitchen, a crib, toys. He'd also shared first words and steps and other major childhood milestones as he and Juleka went back and forth accomplishing them. They shared a single mom who loved them with all the love she had to share and an absentee dad they never knew. All of these were expected but it never bothered him. He loved his family and the closeness sharing had given them. It made him happy.

Thanks to those years, it wasn't a surprise that he was still sharing things now.

He still shared a room and bathroom with his sister. Now he and her shared words of crushes and first kisses along side their love of music. Shared his perspective with Juleka on how to deal with feeling invisible and forgotten. Still shared that single mom who loved them relentlessly but now shared the aching pain and confusing joy of the appearance of their absentee dad.

But Luka also shared other things now as his sharing expanded from his family to his everyday life. He shared the metro with colorful strangers to and from school. Shared lunch with his friends at the music school he'd been enrolled at as soon as he came of age. Shared music teachers and composition classes with other artistically inclined students his age. At home, he shared a band with Juleka's friends, even shared some of those friends with her. He shared with them the music that had been playing in his head since he was a child. The melodies and rhythms that would keep him up during the night that made it hard to sleep from time to time. The harmonies and chords that flowed through his body, screaming to be let out. It all worked out as he shared and contributed to the band's dream of creating a place that was filled with hand bangers and slow drifters, tear jerkers and mood lifters, heart breakers and soul touchers of their design. The happiness his soul knew from sharing this passion was amazing.

Sharing came so naturally that when a blue haired beauty stumbled into his room one day, he couldn't help but share with her the song in her heart. It was music to his ears: as clear as a musical note and as sincere as a melody. She'd seemed stunned but content in the moments where the notes from his guitar hung in the air. Once the sound slipped away, she had shared her name with a small smile with him that made the tempo in his own music increase. Later he would realize that that was the moment it happened: the moment the music in him changed as he fell for her.

After that moment, Luka found he wanted to share more with her. More of... everything. So he did. He shared his music, his thoughts, quick glances, smiles, quiet moments, ice dances, and his heart. She shared things in return such as the pressure she felt from responsibilities he didn't quite understand and the joy she found in designing and creating things. She shared the love and respect she had for her parents and her love for her friends. Every moment they shared led to his feelings for her growing more and more until no one else could share the space in his heart she occupied. Seeing her smile meant the world to him and having her also share her dreams and aspirations with him was everything. Her happiness was everything. It wasn't long before Luka could hear a change in her music (he had noticed it immediately because it had become his favorite tunes to listen to) that signified that she also shared feelings for him. He was there in her heart! But she didn't say anything.

Luka wondered what kept her from sharing how she felt out loud until the day they went to the ice rink. After the akuma was gone and they were leaving, he saw it. He had offered to walk her home and she had looked to the other couple they'd been with and declined. That's when he realized it:

He was sharing Marinette's heart with Adrien Agreste.

The thought didn't bother Luka. After years of listening to other people's music, he knew love was complicated and tricky and wild and that it was possible to love two people at once. He also knew that the other guy he was sharing with wasn't a bad guy. The green-eyed blond was nearly the picture of perfection: incredibly kind, talented, friendly, and good looking. Their shared band practices from time to time had proven so. The music inside of him was the only troublesome thing Luka could think of: something amazingly complex that was being drowned out by a sad piano. Luka always wondered what had caused it to become that way but figured that when the time was right, Adrien would share his struggles with someone he trusted.

Another thing Luka knew was that Adrien didn't seem to know of Marinette's feelings yet, which changed her music when the other boy was around. But Luka also knew that things would work out when she eventually decided to share them. Both of their heart songs shared a simple but important melody that tied them together. Knowing this made sharing her heart so much easier to bear, even with the knowledge that he was only the counter-melody: second to the lead melody that was Adrien. She had loved Adrien first and loved Adrien most. There was no bigger want in her heart's song, so he would do what he could to help her out so she'd be happy. He knew that seeing her happy would make it all worth it. Adrien would make her happy and that's all Luka cared about. He'd grown up sharing and wanted nothing more than to share in the beautiful glow of her happiness, even if that meant they would only share smiles from then on.

Even if that meant he wasn't able to share his pain.
