So for a long time, I've wanted to write a Miraculous fanfic. It's not that I haven't had ideas; it's just hard to remember them long enough to type on my computer.

For those of you who are new to my writing, I'm a YouTube and musical addict who can't seem to shake either habit. As a result, I find a lot of animatics for various songs that I love, like the specific one that inspired this fic that you should totally go watch after you read this story! It's based off "Miraculous Dancing Queen" by SugarberryArt. I don't care if you enjoyed Mamma Mia! or not; I enjoyed it and I'm going to write a story based off it!

Backstory explained later.

"Are you sure, Alya?"

"Positive. It's the only way to get them back together."

"B-but it was sort of my fault…"

"No, I blame her and his dad. Not you and not him. He had no choice and you didn't, either." Alya dropped the envelope in the mailbox. "Now we just have to wait."

"Okay. Whatever you say. We still have to get going if we're going to see her."

"Yep. A plane ride and a boat ride lay ahead, just us and our boys. And her boy."

"Ha, ha. Yeah. Hey, Lila's not coming, right?"

"Of course not! Just Adrien!"

"Good. I don't wanna deal with her, and nobody else does."

"It would kill Mari."

Adrien sighed as he double-checked the date on the invitation.

"What are you so worried about?" Plagg asked. "It's just Chloe and Nathaniel's wedding!"

"Yeah, but… it's not going to be the same without Mari there…"

"I've told you a dozen times, just call her!"

"I can't. Not after what happened."

"That was Lila's fault, not yours."

"Still, I didn't go after her. It's my fault for not doing my job, and now my lady is gone."

"Ugh… give me cheese and I'll listen to your endless pining."

"ADRIEN!"

He looked up to see Chloe standing with Alya, Nino, and Nathaniel by the terminal. They were waiting for him, obviously.

"Sorry I'm late," he apologized. "Nathalie wanted to make sure I looked presentable."

"As usual," Nino laughed. "C'mon, dude. We've still got a boat ride after this."

"Where are we going again?"

"The Island of Love off the coast. You don't get seasick, do you?"

"No, but cats hate water!" Plagg whined. "I'm staying in here." He burrowed into Adrien's bag.

"Ignore him. He's just grumpy because he didn't have camembert yet."

"I get it. Trixx gets that way if she doesn't get her strawberries," Alya agreed. "C'mon. Let's get on that plane. I've just got to get something from the car."

While everyone else headed to the plane, Trixx flew out of Alya's bag.

"You grabbed everything," the fox Kwami reminded her holder. "What are you doing?"

"Well, Marinette's on the island, isn't she?"

"Yeah?"

"Don't you think I should call her and let her know we're coming now so she can have Chloe's dress ready?"

"True…"

"Hello?" Marinette answered.

"Hey, Mari! It's Alya!"

"Oh, hey, Alya!"

"I was just calling to tell you that me, Nino, Chloe, and Nathaniel are on our way to the island for the wedding."

"Great! Can't wait to see you all! Oh, and Chloe's dress is almost ready, too!"

"Mama, who you talking to?" asked a tiny voice on the other end.

"A friend. Go upstairs, okay?"

"Okay, Mama!"

"Okay, Mari, what's going—"

"Gotta go, Alya! See you when you get here!"

There was a click as she hung up, leaving Alya with an open mouth.

Marinette has a child?! Oh my God…!

Marinette sighed as she slipped her phone in her pocket. She felt horrible for hanging up on Alya, but she had to keep her secret. There wasn't any choice in the matter, especially when Adrien was most likely coming, too. It didn't matter that he wasn't with Lila anymore. He hadn't cared enough to go after her when she'd left, or to call her when she told her friends of her choice to leave Paris. It was for her own good and the good of…

"Emma!"

The blonde girl hopped around her mother's legs, her bright blue eyes shining happily.

"Now we play, Mama?"

"Yes, but I have customers coming tomorrow, so be on your best behavior, okay?"

"Okay, Mama!"

At the port, Alya and Chloe got on an earlier boat, due to the fact that they needed to 'transport Chloe's wedding dress' and Alya wanted to see Marinette before Adrien showed up. She had to know what her best friend was hiding out there. Plus, that gave the guys more time to talk.

"So, Alya, what's going on?" Chloe asked. "I mean, you don't seem like the type of person to follow wedding superstition, so something's up."

"Marinette's on the island, and I wanted us to see her again before Adrien gets there. Plus, I called her earlier, and she's hiding something from me."

"Well, let's let her know that we're almost there and to be ready for us."

Marinette watched the people stream off the boat before a familiar pair stepped onto the dock.

"ALYA! CHLOE!" she called.

"MARINETTE!" they cheered, rushing towards her and enveloping her in a hug.

"Girl, you look so good!" Alya complimented.

"The long-haired look suits you!" Chloe added.

"Thanks, girls!"

"Let's get to our hotel and then catch up," Alya suggested. "We've got a lot of luggage to unpack and a dress to try on!"

"Oh, right!"

As soon as they were unpacked, Marinette led her two best friends to her home on the island, where she ran a small dress shop downstairs and lived upstairs. She disappeared into the back to retrieve Chloe's dress, giving her friends plenty of time to look around. Alya looked at everything, and wasn't able to find any clues to Marinette's secret.

"Here it is!" the designer announced, coming out of the back room with a white gown. "Go into the dressing room and try it on!"

"Could you help me?" Chloe asked. "It might be a little big or small…"

"Oh, right! Come on!"

Alya was left alone in the shop. She sat down on a bench and waited for Marinette to come out so she could be interrogated. The superhero/reporter didn't hear the footsteps hopping down the stairs, or the cries of Tikki from the second floor. She didn't even look up for a minute.

"Hello!"

Startled, Alya's head shot up and her eyes landed on a small girl in front of her. The girl had long blonde hair held back by a pair of ladybug barrettes, her bluebell eyes wide and familiar to anybody who knew Marinette Dupain-Cheng.

"Who are you?" the girl asked, tilting her head to the side. Her voice perfectly matched the one that had been in the background of the phone call.

"Depends. Who are you, little one?" Alya inquired carefully.

"I'm Emma Dupain-Cheng! My Mama makes pretty dresses!"

Suddenly, it clicked in Alya's head. Marinette hadn't run because she felt betrayed; she'd left because she was pregnant and didn't want to ruin Adrien's image!

"Well, Emma, my name is Alya. Your mama is a friend of mine."

"She said cutsomers were coming today."

"Yes, and she's helping a princess marry her prince."

"Really?!"

"Yes. Your mama made the princess's dress and she's helping her put it on."

"Is she a pretty princess?"

"Yes, very pretty. Her prince is coming on a boat later!"

"EMMA!"

Tikki flew down and landed on the girl's head.

"You know your mother told you to stay upstairs!" the Kwami scolded.

"But Alya is nice!" Tikki looked at the woman in front of her and grinned sheepishly.

For a few minutes, the trio chatted. It didn't take long before Marinette and Chloe reemerged from the dressing room, Chloe's dress fitting perfectly in every way. Marinette had a grin on her face… until she saw her three-year-old daughter talking happily to Alya.

"EMMA!" she gasped.

"Mama!" the tiny blonde squealed, grabbing Marinette's leg. "Is she the princess?" She pointed to Chloe, who just blushed and looked at Alya.

"Yes… Emma, I need to talk to them in private. Go to Miss Valerie's house and tell her I need her to watch you, okay?"

"Okay!"

Once Emma was gone, Marinette led her two friends upstairs, where she fixed them tea and cookies. Alya was dying to ask about Emma, but refrained until Marinette sat down and sighed.

"Yes, Emma is Adrien's daughter, too. It's why I left Paris. I had some money from the fashion contests I'd won and I used it to buy my shop. Emma has never met her father, and I don't want her to. It'd be too… painful for me."

"Geez, aren't you a ray of sunshine?" Chloe grumbled sarcastically.

Meanwhile, on the guys' boat…

"All right, Adrien, what's up?" Nino asked, frustrated by his friend's brooding. "You've been nothing but moody since we left Paris. Something's going on."

"I have to agree," Nathaniel added.

"Well, it's just… I miss Mari," Adrien admitted. "I wish I'd gone after her, but I didn't and now she's out of my life forever."

"Blame Lila, not yourself, dude," Nino scoffed. "It was her fault."

"I know, but still… we could've been married ourselves by now, maybe had a kid… it doesn't matter. She's gone and I'm never going to see her again."

Oh, Adrien, you poor pathetic boy. Your princess is closer than you think.

So long and thanks for all the fish!
