In the fanfiction, Adrien could regret rejecting Marinette when he realizes how much she truly cared for him. Marinette was always there for him, through thick and thin. Once she's gone from his life, he misses her presence, her laughter, and her little quirks. He might try to reach out to her again, but she's understandably hesitant after being rejected.
Adrien's regret could be a slow - burning process. At first, he doesn't think much of rejecting Marinette. But as days go by, he notices that something is missing in his life. It's Marinette's positive energy and her unwavering support. He starts to recall all the times she made him smile and how she always put his needs first. This makes him regret his decision deeply, and he has to come to terms with his feelings and decide whether to try and make amends.
One possible outcome could be that Adrien realizes his mistake when he sees Marinette moving on with her life happily without him. He might start to notice all the little things he loved about her that he took for granted, like her kind heart and her creative spirit.
In a fanfiction, Adrien could be at Marinette's house for a costume - making session for a school play. He's been so busy lately that his exhaustion catches up to him and he falls asleep on her work table. Marinette would be concerned at first but then realize he really needed the rest. She might then cover him with a blanket and continue her work quietly, stealing glances at his peaceful face from time to time. This moment could be a turning point in their relationship, as Marinette sees a more vulnerable side of Adrien and her feelings for him deepen.
One possible scenario could be that Adrien is over at Marinette's for a study session. He's been really tired from all his extracurricular activities and model work. As they're studying, he gradually dozes off on her couch. Marinette might initially be shocked but then find it endearing.
After getting married, they would become more open and trusting with each other. Since they know each other's identities as Ladybug and Chat Noir, there would be no more secrets between them. Their relationship would be more stable and they would support each other even more in their daily lives and superhero duties.
Once upon a time, Marinette and Adrien's big day finally arrived. The city of Paris was adorned with flowers and ribbons. Marinette, in her beautiful white gown, walked down the aisle. Adrien, looking dashing in his suit, had tears of joy in his eyes. Their friends and family watched with love. As they said their vows, the whole place was filled with an air of magic. And then they were pronounced husband and wife, sharing a passionate kiss as confetti rained down on them.
A great element in such a fanfiction could be the family aspect. Maybe they start thinking about having children. How would they raise their kids? Would their children inherit their superhero powers? And how would they protect their family from the villains in their world? Their friends like Alya and Nino could also play important roles in their married life, perhaps as godparents or just as good friends who are always there to offer advice and support.
Yes, there are plenty. There are fanfictions that focus on their budding romance, like the ones where they go on a cute date or have a heartfelt conversation that deepens their relationship in a sweet and innocent way.
Another reaction could be that Marinette pretends to cooperate with Adrien at first. By doing this, she can buy time and look for an opportunity to escape or get help. She might act as if she is okay with what is happening while secretly planning her next move, like leaving a clue for someone to find her or finding a way to disable Adrien temporarily.
He could also be a bit worried. Adrien might think about the responsibilities that come with having a child. He might wonder if they are ready for this big step, considering their own lives and any potential challenges. He would then sit down with Marinette and have a serious conversation about how they are going to handle everything.
I really like 'Adrien's Discovery'. In this fanfiction, Adrien starts to notice Marinette in a new light. He begins to see all the little things she does for him and how selfless she is. It has some really heart - warming moments, like when Adrien defends Marinette from Chloe's mean remarks. It's a great read if you want to see more of Adrien realizing his feelings for Marinette.
