Luka wondered if it would be too much to introduce the idea to her.

His girlfriend Marinette was prone to panic, but this question has been eating at him even if it was a bit of a bold question to ask when they were still teenagers.

But he just held that thought as the two of them found a picnic table by the flowers. Marinette smiled at him as she opened up the picnic basket and cut croissants in half. She spread cream cheese on both slices and placed blueberries on one slice, and sliced strawberries on the other.

Luka smiled in anticipation. Marinette was about to hand the blueberry slice to Luka. But he took both slices and placed them together before taking a huge bite. He gave pleased noises from the sweetness of the berries and the freshly made croissant.

"Hey! We were supposed to share that!" Marinette teased.

"Sorry," Luka said before wiping berry juice from the corner of his lips. "It tastes so good."

Luka handed the sandwich back to Marinette, and she took a bite herself. Giving multiple pleased moans as she wanted to eat the rest.

After the two of them finished lunch, Luka wiped the last bit of berry juice from Marinette's lips before sucking it off his own fingers.

"That was an amazing lunch melody," Luka said, smiling at her.

Marinette grinned. "Anything for you, Luka."

Anything.

It was at this moment that Luka knew she loved him as much as he loved her. And that made his heart feel so strong. But they were still so young.

The blue-haired boy reasoned with himself to just place that question on the back of his mind for now. He grabbed his guitar before climbing over the picnic table to sit next to Marinette. Luka played gentle tunes as Marinette rested on his side.

God, Marinette's gentle body against his, causing his heart to beat faster and his guitar playing to be more passionate. Whether or not he asked her, he certainly knew his own answer.

"Is something on your mind?" Marinette asked.

Luka lost his tune for a moment. Then, he paused his guitar playing because he had to admit he was a bit nervous right now. Even if he was usually considered the calm and collective person in their friend group.

"Nothing in particular," Luka lied.

Marinette paused before turning to her boyfriend, and her bluebell eyes looked right through him. Beautiful bluebell eyes like a gentle lagoon on a starlit evening.

Luka continued to play that gentle tune to calm his nerves.

"I was thinking about," Luka paused as he tried to keep up his tempo. "How it's a beautiful day today and how I am happy to be spending time with the most amazing girlfriend in the world."

Marinette smiled, but she didn't seem very convinced.

"And I am going to be dreaming about delicious fruit croissant sandwiches for the next few days," Luka added.

Marinette gave a pleased hum. "You always know how to compliment me."

Marinette gave a devious smirk and booped his nose for a moment, causing Luka to smile. Yes, she was charmed by Luka's energy, but she knew he was stretching the truth a bit.

But Marinette let him be as she laid beside him and relaxed to his soft tunes while lacing some flowers together. When she finished, she took a moment to sit up and tie them around Luka's neck.

He smiled, thinking about how she was always sweet and giving.

Little did she know she had a question weighing on her mind as well.

"Luka…"

Luka's aquamarine eyes shined at her. Something that still made Marinette blush rose-red even though they were long past the honeymoon phase of their relationship.

"Yes, Marinette?" He set his guitar down for a moment as he loved hearing her voice much more than any instrument.

Marinette smiled sheepishly and placed her hand on the back of her neck, automatically feeling that she was sweating.

"Well, we have been dating for a while, and…."

Luka waited for her to collect herself, but Marinette still felt so nervous.

"I was going to ask you something crazy," Marinette said.

Luka gave her a calming smile. "I doubt what you have to say is crazy, Marinette."

Marinette blinked. "It is! Because we are still teenagers and…."

She suddenly felt her words stop. Marinette gave a soft sigh as if she gave up.

Luka breathed out and felt he should reveal what he wanted to ask her. Maybe it would make her feel less crazy. He was still a bit worried Marinette would be turned off by the idea, but if this idea was eating at him for, a while he should let it out. If it really was a bad idea, his gut would tell him not to.

He placed his hand under her chin and raised her head up to meet hers.

"I wanted to tell you something too," Luka said as Marinette's bluebell eyes widened. "But," he paused from his voice shaking a bit. "I am a bit nervous…."

It clicked for Marinette that he was about to tell her what he was hiding before. Marinette moved closer to him.

"Don't be nervous!" Marinette insisted. "I want to know!"

Luka chuckled to himself as his hand dug through his jacket pocket.

"I am afraid you might be a bit overwhelmed," he said gently.

Marinette knew she was prone to panic, no one had to tell her that twice, and Luka always made her feel comfortable and stable. She took his free hand with hers.

"You can tell me anything too, Luka!" Marinette cried, her eyes showing him that she was serious. "You always know what to say."

Now Luka suddenly felt at ease as he squeezed her hand and moved closer to her, so they were leaning against each other as if they sat in a love seat.

"I'll tell you," Luka said.

Marinette rested herself against Luka's shoulder as they sat in silence for a moment before Luka spoke.

"Well, we've been together for a long time, and I couldn't be happier," Luka said.

Marinette gently nuzzled herself against him. "I couldn't either! You're the best boyfriend ever, Luka!"

That was a relief for Luka to hear.

"But for the past few weeks, I couldn't help but think…."

"Hm?" Marinette raised her head to meet Luka's eyes. Her blue eyes sparkled to him, deep in curiosity.

"That maybe in the future…." Luka's face started heating up. Marinette squeezed his hand as if she was eager to know what he had to convey.

Luka breathed out as he tried to compose himself but looking at his beautiful girlfriend now, he smiled at her without a single doubt in his mind.

"I love you, Marinette," he said firmly. "And there is not a single doubt in my mind about that. But for the past few weeks, I couldn't help but think it would be absolutely amazing if we…." He dug into his pocket again.

"If we got married someday in the future."

On the one hand, Luka was relieved he freed that burning idea. But now, he started to question if he was a weirdo hopeless romantic.

But Marinette's mouth went slightly agape before she placed her hand over her chest and smiled warmly.

Luka guessed she wasn't upset at all, but she said nothing and dug through her backpack to pull out her sketchbook.

"I was a bit nervous because of what you were hiding," Marinette said as she held her closed sketchbook in her hands and leaned against her boyfriend. "But…"

She opened up her sketchbook, and Luka saw drawings of the two of them in adorable chibi anime style and wearing wedding attire. There were also the words "Marinette + Luka Together Forever" written in cursive.

Luka held the other side of the sketchbook. A pleased smile was on his face that made Marinette feel relieved.

"Alya and Kagami teased me again this as if they don't fantasize about marrying their own boyfriends!" Marinette cried.

Marinette retook Luka's hand and blushed bashfully, thinking about what could be in the future.

"But the point is," Marinette's face glowed brighter red. "I would love to marry you someday, Luka."

Her voice made a slight squeak saying that last part, but Luka adored that.

Marinette couldn't help but giggle next.

"It's funny how we both thought the same thing. I'm not an insane hopeless romantic!" Marinette cried.

Luka wrapped his arm around her and held her close to where she could faintly hear his heartbeat like a soft metronome.

"Kind of makes me believe that the both of us are made for each other, and we will get married when the time is right," There were hopeful notes in Marinette's words.

"I'm glad you agree, Marinette," Luka said. Marinette just wanted to rest by her boyfriend's side for the rest of the day, feeling secure for the future.

"Because I got you this."

Marinette turned and managed to stifle her yelp at the sight of Luka smiling down on her and holding a ring with a pink heart-shaped jewel on it.

"Luka!" Marinette cried. "You…" She became breathless.

Luka held her closer. "It's just a promise ring. I thought it suited you."

Marinette released herself from Luka's hold and gave him a slightly stern look.

"Luka, I told you you don't have to buy me expensive things."

Luka smiled. "I know, I saved up for this."

"You're more than worth it, though," He said as he moved the ring closer to her.

Marinette looked at the ring for a good moment. It was absolutely gorgeous and priceless, and Marinette almost felt she wasn't worthy of such a romantic gift. Not to mention all the money Luka put in for her, so she couldn't bring herself to accept the ring.

But then Marinette thought, this boy truly was ride and die for her. Even willing to buy expensive, flashy stuff to show how serious he was about them. And this was a dream come true for Marinette. No, more beautiful than any other dream she ever dreamt.

And she loved him. Her concerned expression melted as her heart skipped a beat, thinking how much Luka believed in what they had.

She smiled as she presented her finger, and Luka placed the promise ring on her.

Marinette was in awe, looking at the small diamond that was now wrapped around her. She just felt so lucky being loved this much, and she almost wanted to show it off to all her friends as if it were an actual engagement ring.

But she turned to Luka, who gave her his usual "I love you" face. Everything he did reminded her that she was loved.

"I love you, Luka."

Luka's aquamarine eyes shined like the sea, and his smile was as warm as sunlight.

"I love you too, Marinette."

Marinette moved in closer, so she sat on his lap and hugged him while resting her head on his broad chest. Luka gently hugged her as well, and they stayed in blissful silence for a moment.

Then Marinette broke the hug and eagerly jumped off the picnic table to pack up the picnic basket.

"Luka, let's go get ice cream."

Luka had to admit that sharing Andre's ice cream did seem perfect after he and Marinette made a promise. And he was craving more sweet stuff.

"Sure, Marinette."

Luka placed his guitar in his guitar case, and the two of them walked hand and hand.

But feeling Marinette's ring on her finger gave Luka even more blissful daydreams of a beautiful future together.
