Can somebody write a Merthur where everything is the same (with happy ending) but Merlin never tries to hide his magic from day one and openly talks about it but Arthur just thinks he's joking or talking bullshit, and when it happens the first time in front of the Knights they're all "wtf Arthur's new manservant has magic and we just accept it? Ok" but then it becomes a running joke, and by the time Merlin actually publicly saves Camelot with magic in front of everyone it dawns on them that it's not actually a joke
