In Another World (Miraculous Ladybug)

Prologue

Nino and Marinette couldn't remember life without each other. They had been friends since birth. Caral had met Sabine at a coffee shop shortly after Sabine moved to Paris. Caral and Tom had grown up in Paris together. So naturally, when Carol learned that Sabine loved baking, was a skilled decorator and needed a new job to stay in Paris, she introduced the two. Tom was a caterer and working on opening a bakery. He had hired James to help him update this building he had bought. The main floor was a storefront, while the upstairs was a home. Slowly a friendship formed in this group then weddings and soon babies.

Nino was born a month before Marinette and soon the parents had built-in babysitters, they swapped date nights. And Marinette spent many days at Nino's house because Caral was a great babysitter. However as the two grew, it becomes clear, Nino had no rhythm and Marinette needed coordination. So their parents put them in an after-school dance class. And Nino did find rhythm and a passion for music. It did not work out as well for Marinette, the girl had no grace in flats, but put her in heals or point shoes and she could fly. Her teacher couldn't understand it. Eventually, the two kids landed on ballroom dancing as their favourite. They had a trust and bond that made them great partners. As they grew up, swing and waltz become their favourite to do for the yearly showcase. They had thought about becoming a competitive team, but their teacher had them helping with the music mixing and with the making of costumes. So they worked out a deal, they got a free dance class and practice space every Saturday in exchange for helping out (and gaining some job experience) and whenever their teacher needed a duet for a showcase or something they were her go-to team. 

Everyone thought these to would end up in love, their families were close, they even when on vacation together. It seemed that the two kids could read each other minds, they moved as one, hardly needed to talk. Everyone shipped then as it were, that was until Adrien and Alya showed up, on the same day, that first day of school changed everything. 

Moments after the gum insitent...

"Nino right?" Adrien asked after Marinette snapped at him. 

"Yeah dude, that's me." Nino knew what was coming. 

"You saw that right? I was trying to take it off." He looked down.

"You could have said that dude." Nino sighed.

"I... Chloe is my only friend..." He fidgeted. 

"Dude, that's wrong on so many levels. Mare happens to be my best friend, so I'll save you." he patted Adrien on the back. 

The new version of the Umbrella Scene 

"I can't believe I forgot my umbrella Tiki." Mariette sighed. Tiki didn't have time to answer because Adrien stood next to her. "Adrien?" The boy smiled at her. "Look Nino and I talked, I'm sorry, I was mad the Chole made me move, she's been bullying me for years and Nino finally moved upfront so that was gonna be so fun. But that's not important, I shouldn't have let my temper get the best of me, and I would like to be friends." She reached out her hand.

"I would like that." Adrien reached his hand out too. He smiled as their figures touched. He guested for her to follow him, she did. As they walked towards his ride, "Would you like us to drop you off?" 

"Oh no, I live right there." She pointed to the bakery a little less than a block away. "It will be fine." 

Adrien then handed her his umbrella, "You can return it to me tomorrow." 

The rest of the scene plays out in the show. Except for Marinette is a touch more confident around Adrien you know more like a normal girl would be in real life.

New Version of the Zoo date

Nino knew everyone and school shipped him with Marinette they weren't exactly suttled about it. And yes while he had liked her in the past, he knew she liked Adrien. She admitted as much after their talk on the second day of school. Sure it burned him that his best friend liked his new best bro and not him, but the more they got to know Adrien he could see why. For being locked away most of his life he had the biggest heart. And he admitted to Marinette that he wanted to get to know Alya better. Mari was more than willing to help him get to know her new best gal pal.
