The month of love inspired Marinette to go old-fashioned and write the most adorable love letters for her boyfriend. She used one of her many floral stationery that she drew musical notes on before writing.

"Just telling you that I love you Luka! You're the sweetest boy I've ever known and you will always be my muse! ~Your Melody, Marinette!"

She printed a few blue hearts before putting the letter in an envelope. And she sealed the letter with a blue heart sticker. And thankfully Marinette had the best mail system in all of Paris. Tikki was super eager to go on a mail delivery mission. Marinette also attached a tiny decorated bag of pistachio macarons (Luka's favorite!) as she hummed one of Luka's songs, putting the finishing touch.

"Is it ready Marinette?" Tikki cried.

Marinette smiled down at her kwami. "Yes, it is Tikki."

Tikki excitedly took a moment to perch herself on Marinette's hand.

"I'll make sure it goes to Luka's house safely!" The little kwami cried.

Marinette grinned before nuzzling Tikki against her cheek. Tikki responded by giving Marinette a little hug.

"I trust you," Marinette said.

And Tikki certainly felt carefree as she carried the envelope and the macarons while flying around Paris. The sky was blue, the clouds were beautiful, and Tikki couldn't help but sing one of Luka's songs off-key.

But eventually, Tikki flew closer to the city, and civilians noticed a flying love letter. It was either the annoying commercialism of Valentine's Day or the daytime drinking some adults were doing.

"Coming through!" Tikki cried as people gasped at the love letter flying by.

Even if people were confused, Tikki took care of the situation delicately. She didn't know where The Liberty was, but she would surely find it.

Then a few little boys seemed hungry for pistachio macarons.

"Hey, look there!" A little boy cried while pointing.

Four wide-eyed boys saw a delicious-looking Valentine's treat floating in plain sight, and they couldn't help but reach out for it. Just then, Tikki finally realized she was too reckless and lifted the gift and flew higher.

"Sorry boys! This is for Luka!" Tikki cried before flying back up into the sky.

The boys stopped as they watched the letter and treats flying into next year.

Tikki sighed as she felt content flying in empty skies.

"That was close!" She cried.

The little kwami felt guilty though, she didn't want to ruin Marinette's trust.

"I promise I won't cause any more trouble!" Tikki cried.

But before Tikki knew it, it seemed that trouble was finding her as a few pigeons were flying in her direction.

The little kwami cried as she tried to fly away and tried to shield the letter and macarons with her tiny body.

"Miss Tikki!"

"Huh?" Tikki cried.

One of the pigeons flew towards her but stopped flying in place. Perched on the back of the pigeon was Sass the snake kwami.

"Master Sass!" Tikki cried.

The snake kwami smiled at her. "Good morning Miss Tikki. Is everything going well?"

Tikki grinned. "Oh everything is going fine Master Sass! I am just delivering a letter and macarons for Luka!"

Suddenly Sass dismounted the pigeon and flew to Tikki.

"Oh Miss Tikki. If you were to deliver a note to my Master, you should be a bit more careful."

Tikki frowned slightly as she held the gift close to her. "I know…"

Sass took the love note from Tikki, leaving her with the bag of macarons.

"Come Miss Tikki. We can deliver the letter to Master Luka by pigeon."

Tikki giggled before twirling around with red sparkles. "Sounds like fun!"

The ride to The Liberty was much smoother. The pigeon safely landed near Luka's open window, and Tikki dismounted with the letter and macarons in tow.

"Luka!"

Luka was sitting on his bed with his guitar in hand, but when he heard Tikki's voice, he smiled and placed his guitar down before getting up and heading to his desk. The two kwamis greeted him, and Luka smiled at them as he rested his head on his hand.

"Hi Tikki!" Luka said.

"I got a delivery!" Tikki cried as she floated and landed on Luka's desk. She presented the letter and the macarons to him. "Marinette made it special!"

Luka took the envelope and bag of macarons. His heart was warm with how his beautiful melody made the most beautiful and thoughtful gifts. He took a moment to pet Tikki's head, causing the little kwami to purr and blush, similar to Plagg.

"Thanks Tikki, Luka said softly.

He untied the bag of pistachio macarons and handed one of them to Sass, who happily took it and ate it while sitting on Luka's desk.

Luka gently peeled the blue heart sticker that sealed the letter and removed the love note inside the envelope.

Reading Marinette's sweet words didn't compare to hearing her voice, but he still fell in love again as he placed his hand over his lips.

When Sass finished eating the macaron, Luka took another for himself, but an idea came to mind.

"Sass," Luka said.

"Yes Master!" Sass said as he quickly rushed to Luka's side.

Luka held out his hand, and Sass obediently perched himself.

"Do you think you can send a reply to Marinette?" Luka asked with a smile.

Sass grinned in return. "Of course Master!"

Tikki giggled and flew right beside Sass. "We both can!"

Meanwhile, at the Dupain-Cheng Bakery, an influx of little boys visited to eat some delicious macarons. Marinette's father called from downstairs and asked for help, but just as she was about to head downstairs, she heard a tapping on the window.

Marinette was surprised to see a pigeon of all creatures greeting her. Still, when she opened her window, she saw Tikki and Sass riding on top of the bird with a love letter.

"Marinette! You got a reply!" Tikki cried as she flew over to Marinette with the letter.

Her kwami perched on her hand as she presented the love note. Marinette happily unsealed the envelope to reveal one of Luka's many declarations of love to her.

"Marinette my Melody! Thank you so much for your beautiful letter. But the sweet words you wrote are nowhere as sweet as hearing your voice. I can't wait to see you again, my beautiful Melody. ~Your Muse, Luka."

Marinette giggled and jumped around as she held Luka's love letter close. Tikki and Sass happily flew in circles around her.

Old-school romance would never die as long as the Melody and the Muse and their two kwamis were around.
