Luka x Adrien's Sister! Reader

(A/n)- This was requested by @Mslz11. Go check them out! Also, this is a little bit different than the last Luka x Adrien's Sister oneshot. Thanks for reading!

You walked home from the library. You didn't like to be picked up by the limo with Adrien so you used the excuse of going to the library to stay back. It's been working for years now.

With you was Luka. He was your best friend. He always walked you home like this because his ship was on the way to your house.

"So, wanna jam at my place later?"

You turned your head to him and smiled. "Of course! But what about Adrien? He's gonna be all like, 'You can't go over there'." He laughed at your impression.

"Just sneak out." His words echoed in your head. It didn't sound so bad, but how would you do it?

"What time is this jam session?", you asked. Luka thought about it for a moment. "Hmm, I guess at eight?"

You nodded your head in agreement. That would give you enough time to sneak out because Adrien falls asleep at seven. It was settled.

You rounded the corner and neared your house. You bid goodbye to Luka and entered the huge gate. Luka walked away while you went to your room.

You shared a room with Adrien because before your mother passed, she wanted y'all to be close. Her plan worked perfectly. You just wished she could've been here to see it.

Adrien was standing by the window. "Hey, bro. What's up?" He turned around flustered. (Thinking about Ladybug, Adrien?)

You chuckled and went to your bed. "Nothing. I saw you with Luka. Why do you hang out with him so much?" You didn't think anything about it until now.

"Hmm, I guess I just like his company. He is my best friend after all." Adrien rolled his eyes and smirked. "Sure. Best friend"

He did quotation marks with his fingers. You nudged it off and didn't say anything further. You did like Luka once, but you saw him flirting with Marinette and stopped crushing.

As time passed by, you waited impatiently. You couldn't wait until seven p.m. came. It was 6:45.

Adrien got ready for bed and when the clock read 7, you bolted out of the room. You snuck passed the security cameras your dad placed around the mansion.

You ran out of the house and made your way to Luka's ship. He was on the deck waiting for you. He led you up the ladder and to his room.

You saw all his guitar picks and smiled remembering the Jagged Stone pick he gave you. "Here's your guitar." You turned around to be met with Luka's blue eyes.

You grabbed it from him and sat on his bed. "Which song are we playing next week?" Yes, you were in his band.

For the past 4 weeks, you snook out at seven and went to Luka's place. Today you planned to do the same. You walked past the gate and waved at Luka.

When you got inside, Adrien was waiting for you. He was glaring. You tensed at the uneasiness.

"Hey, bro.", you said with a voice shift. He tapped his foot with his arms crossed. "Tell me why you're sneaking out of our room at night."

You sighed for you knew what was to come. You slung your bag to your feet and stared at him. "I've been learning new guitar moves."

He didn't look convinced. "With who?", he interrogated. "Luka. Have a problem with it?"

You would be mad if he did. Luka was your friend and Adrien for some reason didn't like him. "Yes, in fact, I do. That kid is bad news. He lives on a pirate ship for crying out loud!"

That's it, you thought. You marched out of the house and passed the gate. Adrien chased after you but you easily out ran him.

You made your way to Luka's ship and climbed the ladder. Marinette was there, cleaning the stage for the upcoming concert. She was with Luka.

Something hurt in your chest but you nudged it off. You made your way over to them and waved. "Hey, guys. What's up?"

Marinette blushed as she glanced at Luka. You quirked an eyebrow. "Um, (Y/n)?"

You brought your gaze towards Luka. He averted his eyes from yours, embarrassed. "Uou know how I talked about wanting a companion?"

You nodded your head not understanding. "Yeah, but what does that have to do with anything?" He scratched the back of his neck.

"Marinette and I are a couple now."

It hurt for some reason to hear that. You tried to play it cool and congratulated them. Your voice was a little shaky, but luckily they didn't notice.

"I have to go."

You ran off the ship and climbed down the ladder. Adrien was waiting for you at the bottom and had his arms crossed. He started to talk until you ran past him.

(A/n)- There will be a part 2 to this sometime. I don't know when but if you liked it please tell me so in the comments and vote. Thanks for reading! Bye for now!
