Ya, this one isn't gonna have a song, I doubt anyway. But people want to know what happens next so here we go the first (and probably last) songless songfic! :) 

The second they went to the movie they changed everything. That night she had a meeting with Chat. "My Lady! To what do I owe this pleasure?" 

"We need to have a chat." She sat down and Chat looked at her a little scared. "So I have a boyfriend now who I love a lot. And I realized how hard it is to date with all the secrets. So I have a suggestion." 

"Way to drop a bomb and me my lady how long have you been dating?" He leaned in sharing a sad smile. 

"We've been dancing around it for a while but we finally when on a real date and I love it." she looked away and smiled.

"You really love him don't you?" She nodded. "You look so relaxed My Lady, I can't be made a little jealous but I love you enough to not stand in your way. And if I'm honest I've been seeing someone too, and ya this is hard." 

She took his hand, "That's so mature of you Chat." She was kinda surprised, she expected him to fight more, but she did remember at this point Adrien was in a rough spot so maybe she'd pick the right time. "Do you think your girl would want to be a hero?" 

He paused, "Yes, she would be very good at it. She would be perfectly suited for the Dragon." 

"Would she be a good confident for you?" She squeezed his hand. 

"Oh yes. She can keep a secret with the best of them." He smiled. 

"What if dating doesn't go well? Like if you fall apart, would your secret be safe?" She needed to know how much Adrien trusted who she believed to be Kagami.

"Oh yes, she values honour in the highest regard, and to be honest my lady the only reason I was hesitating with her, was you. I don't think I'd leave her, at least no while Hawkmoth is at large, maybe if our paths took us in opposite directions. But our parents would love us to be together. 

"Good then here you go." Using her Yo-yo she pulled out the dragon's miraculous. "Give it to her, and show her who you are, keep it a secret you two will hold you're secret and he and I will hold our secret. If she is a former miraculous holder tell her to change her look so I won't be able to identify her, I'll have my partner do the same, so you can't figure it out." She gave him a teasing smile. 

"Can I still call you My Lady and Bugaboo?" He teased her back. 

"Only if she's okay with it, though I like My Lady better than Bugaboo." She giggled. 

He smiled at her, "Then I'll only ask about My Lady then."

Luka and Marinette found that being public about their relationship stopped a lot of the earlier Akuma didn't happen. There was not Truth or Lies or Gang of Secrets. Alya never learned the truth. Nino never lost it on Cat Noir. When Hawkmoth trapped them at the fashion show Luka and Kagami were already there and able to help. Marinette was able to help Chole when the film thing broke out. She helped Zoe feel welcome without displacing Chole. She never handed her the bee miraculous again, but she gets to hold the Fox miraculous from time to time because Ladybug didn't give any of the old holders their miraculous back, she was just worried about something going really wrong. 

 And when Grand Master Su-Han came knocking on her door, he seemed to know and understand what she did. He also taught her a magic spell to revoke a miraculous holder right to hold a certain miraculous. He had learned it after they had defeated hawkmoth. Luka and been with her when he had told her this information, "Wait, so we could expose Hawkmoth without the risk of Adrien being akumatized?"

"Yes, you could, so he would still have that trama but he wouldn't hurt any of you. And that might save him some of the guilt." He patted Marinette on the shoulder, "If you can, find him a place of Paris to go, I would recommend it. Staying in Paris could be hard for him." 

Luka and Mari brainstormed ideas they could offer him, these were all backup plans if Kagami and her mother didn't just go back to Japan and take him with them. One thing was for sure, Mari would give him Kaalki or offer him access to her whenever he wanted to visit Paris. 

LadyBug, Viper (Formally Viperon), Chat Noir and Tanit (Formally Ryuko) met and had a meeting. "We need to get Shadowmoth out in the open and take his miraculous away." 

"How everything we've tried in the past has failed." Chat leaned back and smiled at Tanit who blushed. 

"The Grand Master of the Miraculous taught Ladybug a spell." Viper explained pulling her close to him. 

"Look we've been a team for six months.  We are a tight well-oiled machine but won't we need more holders?" Tanit offered. 

"I have been thinking about that, and I agree. But not many of them aren't as trained. So here." She handed Viper the Horse miraculous, to Tanit she handed the Fox miraculous, to Chat Noir she handed the turtle miraculous and placed the bee miraculous in her hair. "We are gonna practice the plan." She smiled. 

The took a month and had it down to a smooth plan. They called ShadowMoth out to battle. He met them at a field. Rouge Dragon created an illusion of the four of them. While ShadowMoth was distracted, Ladybee paralyzed him. Turtle Noir shielded him just in case the venom wore off. Winged Viper opened a portal for Ladybee to grab the Miracle Box and then grabbed Roger to make the arrest. Once she was back she set the box on the ground. She stood with her eyes closed, "Met for good, power created for the greater, not for the worst, you are not worthy of the power you hold, whether you allow it or not, Transmission is not yours to wield you can hold, Emotion, not yours to manipulate, powers return to me." As she finished the words she saw the powers drain from him. She turned to Viper "Now!" 

Winged Viper divided Kaalki and Sass, he tossed Kaalki glasses to Ladybee who quickly become Pegabug. "Tanit hold him, trust me!" Ladybug didn't care if her friends question things, they could just think this was a second chance. "Chat give me the turtle, trust me." Chat didn't even have to think he did it atomically. Viper quickly unified Wazz and Sass and put Roger and the detransforming Gabriel Agrest in a cage so he couldn't run away. As soon as Chat Noir saw his father he collapsed into Rouge Dragon's arms. Viper ran and help him close. Hiding his reaction for Gabriel. 

Roger stood shocked and quickly arrested him, just as the venom wore off. "Gabriel Agrest you are under arrest." Pegabug took them to the station using a portal and let the police do their job. She made them promise to say nothing till she and the other heroes got Adrien Agrest out of Paris. No sense wrecking the boy's reputation because of his father's choices. He agreed. 

She returned and hugged the boy. "You two knew somehow, didn't you?" Chat looked up at him. 

"Second chance lets me see a lot, Adrien. Scales in." Luka dropped his trasroamtion. 

"Spots in." Marinette smiled at her friend. 

"Long Open Sky." Kagami kissed her boyfriend. 

"Claws in." Adrien looked at his friends. "What do I do now?" 

"Luka and I knew for a while now but couldn't risk you getting akumatized. So we came up with some plans, but we thought maybe you would want a change of look, maybe a name change, and starting over with Kagami somewhere else. Your mother will likely want to get away from the scandal.  So we thought we could help." I could give you Kaalki a to could and you two could back come and visit whenever you wanted." Mari took his hand. "You deserve to get away from it all for a while and get help, Kagami can be strong for you." 

"My mother is also Adrien's secondary guardian. She insisted once we started dating so that way Adrien and I would not be separated and sent to his aunts." Kagami hugged Adrien tighter. He shook with tears. 

"Can I take my mother's name?" He spoke so softly. 

"I think that's beautiful." Luka squeezed his shoulders tightly. 

"Émile Graham de Vanily. That's who I want to be now. Luka?" He whipped his nose on his sweater, looked at him, "dye my hair black? And if Gami won't hate me can we do green tips? You know have some fun with it?"

Kagami growled, "Only because I love you."

Luka ruffled his hair. "Of course my guy." 

"I'll also transform and head home. Mothers think I'm fencing. I should be home when He gets there." Kagami kissed him love with passion. 

After explaining everything to Kagami's mother and saying that they contacted Adrien's closest friends to help him get ready for the move. They would keep it a secret so no one would know what happened to Adrien Agest and he could reach out to his friends in Paris when he was ready.  She didn't argue with the heroes. Adrien handled himself perfectly. 

Mari and Luka landed back in her room. "Is he gonna be okay? It's like he turned off his emotions..." Mari wrapped her arms around Luka. 

"He's never been allowed to feel. Once they get to Japan and Miss Tsurugi will get him some help. She might be cold but she's not stupid and this might open her heart up more too. They quickly gathered everything they need to help Adrien, and head over there. 

It only took a week to get Émile out of the country. Once Nathalie was found out to be adding Gabrial she offered to set everything right for Émile. So with a new name, new hair colour even coloured contacts, and a new set of MCD originals he left hand and hand with Kagami for a fresh start in Japan. 

The four friends saw each other thanks to the miraculous every few weeks. Luka and Mari would go to them. Émile wasn't ready to face Paris again.  Émile Graham de Vanily become known as an up-and-coming photographer around the world. He ditched the coloured contacts and hair dye after about a year when the world stopped looking for Adrien Agreste. His father's company had been liquidated to pay fees and damages to the people of Paris, the court did give Émile some to start his new life, he instead his house be sold the funds be given back to Paris as well. His father's insistence on his modelling had given him more than enough to have a good shot at whatever life he wanted. When he turned 20 he married Kagami, their wedding had been small but so beautiful. Marinette design both dress and suit, Luka and Mari stood up as key witnesses, Alya and Nino who had eventually been let in on the secret once Lila had been exposed (thanks to Gabriels willingness to throw everyone under the bus) and they had to earn Mari's trust back were also there. Six months later Kagami and Émile did the same thing for Luka and Mari. And after almost a decade away from Paris Kagami and Émile moved back to work for MCD Designs as a Photographer and Marketing/Promo Manager. 

It helped that both women were expecting their first and wanted to be closer together, Émile also missed his old friends and with Alya, Nino, Mari, and Lukas help he met then again, this time as Émile Graham de Vanily and if any of them suspected he was their long lost classmate Adrien Agreste they never said a word to anyone. The four friends lived lives that made them so happy, Luka after having a life on the road in one timeline chose to live out his dream of making instruments in a shop next door to Mari's headquarters, he also was able to teach music in that same shop. Everyone got a better life and for that he was greatful. 

And when that faithful day rolled around each year Luka and Marinette would share a kiss and thank their lucky stars that they went back in December. 

AN I hopped you liked this ending!
