Social expectations could also pose a challenge. They are from high - society families, and there are certain standards and expectations. They may have to deal with family - imposed events and traditions that they don't necessarily agree with, which could put a strain on their relationship.
Nate could be a great addition. He could be a confidant to either Chuck or Blair, and his own storylines could intersect with their married life. For example, if he gets into a business deal that affects Chuck and Blair's business.
You can start by looking on popular fanfiction platforms such as FanFiction.net or Archive of Our Own (AO3). Just type 'Chuck Blair married' in the search bar and see what comes up. But again, if this is a very specific or less - known concept, you might not get many results immediately.
I'm not sure which specific 'Chuck Blair' you are referring to. There might not be a very well - known 'Chuck Blair' in mainstream media. If it's a more niche or original character created within a certain community, it would be difficult to recommend without more context. You could try searching on specialized fanfiction websites like Archive of Our Own (AO3) and use relevant tags to find stories related to this 'Chuck Blair' marriage.
There could also be other supporting characters from the original series. For instance, Serena van der Woodsen might be a significant character in the fanfic. She could be Blair's best friend and offer advice or create some drama in their married life. Nate Archibald might also be involved, perhaps as a business partner to Chuck or an old acquaintance who causes some tension in their relationship.
Another plot could be about them starting a family. The difficulties of pregnancy, raising children, and how they balance their busy lives with their new family responsibilities. There could be drama with in - laws and different parenting styles, but in the end, their love for each other and their family prevails.
Before marriage, they had a more on - again, off - again relationship. In marriage, there would be a sense of permanence. They would have to be more committed to working through their problems instead of just walking away like they did in the past.
A really cute scenario could be them adopting a pet together. Since they both have a bit of a wild side, they might adopt a rescue dog that is a bit of a handful. Watching them learn to take care of the dog and seeing how it changes their relationship for the better, like making them more patient and loving towards each other.
Serena is often a popular character in these fanfictions. She might be Blair's maid of honor and get involved in all the pre - wedding drama. Nate could also be a prominent figure, perhaps as Chuck's best man, and his relationship with other characters can add more depth to the story.
Chuck might be initially shocked. He could stand there in disbelief for a moment, his eyes wide. Then, he might pull Blair into a tight embrace, whispering that they will face this together.
