Heya. So while exploring AO3 and Tumblr I came across a pairing I actually really like. I didn't expect to like it but then it sparked something in me so here we go.

...

"Enough Hawkmoth. Just surrender the Butterfly Miraculous." Ladybug shouted. She swung her yo-yo at her side. Ready to grab him at any moment. Chat stood by her side with his staff in hand ready to attack whether it be with the staff or pouncing at him to snatch the miraculous off his chest.

"We know who you are there is no getting away with this." Chat Noir was furious. Ladybug was too but she wasn't sure why he seemed to be taking it personal.

"You foolish children. I will get your miraculouses and when I do I will get what I want." Hawkmoth was overly confident for someone who had nowhere to escape to.

"Yeah? What's so important that you must terrorize all of Paris and risk everyone's lives? What's so important that you throw away what little of a relationship you have with your son? That you attack his friends? That you are willing to kill for?" Chat snapped at the man. He himself was a man in his own respect now. He and Ladybug are 18. They had been battling Hawkmoth since they were 13. Ladybug was made the guardian of the Miraculouses when she was 14 because Hawkmoth was going to kill Master Fu if he didn't hand over the Miraculouses.

"Chat…" Ladybug said. She turned towards Chat who had taken a step towards Hawkmoth. She wasn't sure how to comfort her dearest partner. Both of their miraculouses beeped signaling they were close to detransforming. Chat had one minute while Ladybug had two minutes left.

"My wife." Hawkmoth said he turned away and looked out the broken glass window of his observatory. "I'm going to bring her back to me."

"Don't you dare talk about her!" Chat yelled.

"I will do whatever it takes to bring her back. Even if it means I have to... kill in the process." With his back to the two he quickly unlatched the lock on his cane that held the sword in the wood that concealed it. He swung around when he paused and continued as he lunged towards ladybug and stabbed her in the abdomen. The magic of the miraculous had made the sword enter in a safe place just away from any of her major organs. Hawkmoth knew this was a possibility so he pulled the sword up and made the through and through go further length of the cut went from just above her pelvis to just below her rib cage.

"LADYBUG!" Chat shouted and lunged at Hawkmoth. Hawkmoth released the sword to prepare for the attack and Ladybug fell to her knee. His detransformation began. Hawkmoth grabbed the young adult's arm and swung him out the window. Just as he was about to go over the window sill he was 100% Adrien Agreste. Both Ladybug and Hawkmoth rushed to save him. Ladybug, despite the sword still being in her she swung her yo-yo to wrap around one of the glassless window panes and allowed herself to plummet to the ground. She had just got ahold of his hand when he hit the ground. Both Adrien and Ladybug's eyes shot open as the crunch that came from his body made it clear what his fate was. Marinette detransformed and fell the last foot to the ground and landed right next to Adrien.

"Adrien!" Marinette cried. "Please!Please! Oh God! No!" She didn't know what to do. Plag and Tikki had been exhausted and laid on the ground between their two owners. She grabbed ahold of him, despite the pain she was feeling and tried to carry him. She wasn't able to.

"My son!" Hawkmoth cried out. He detransformed and turned to Marinette. "What have you done?" He blamed Marinette. The blade in her abdomen had disappeared with his transformation.

"M-M-M'La-Lady…" Adrien mumbled. His voice was raspy and Marinette set her hand on his.

"It'll be ...okay... " Marinette tried to hold back her brought her hand to his lips.

"I-I lo-ve you. I'm… sorry I didn't re-realize so-sooner. I don'-t regr-" His words stopped as he fought for air. Marinette shot up. She ignored her pain and grabbed Hawkmoth's Miraculous, freeing Nooroo, and with the kwami's consent she transformed. Mid thigh grey boots, a deep purple romper, and a matching grey trench coat with purple trim held together by the miraculous.

"I got you don't worry. Nothing is going to happen to you." Marinette held back as many tears as she could.

"I...I don't r-regret it. I l-love you... so much. B-both sides of you. Always... have." Adrien held his hand to her cheek.

"I-I love you too." She smiled even as the tears fell. Her voice squeaked and broke as she spoke. She landed in front of the hospital and dropped her transformation. Nooroo hid in the purse that sat on Marinette's hip with the other kwamis. She held him as close to her as she could and held him with all her strength. "Help we need help!" She shouted in the ER. No one turned towards them. "It'll be okay. I got you. Just hang on." Marinette tried to comfort Adrien. He brought his lips to her's, giving her a chaste kiss, and gave her a weak smile then fell limp in her arms. She screamed for help as loud as she could and finally was able to get attention. People rushed all around her and Adrien as soon as he was removed from her arms she passed out.
