An interesting crossover that will not make sense a lot of times, but just roll with it.
You are part of the seven deadly sins and fell in love with the Boar Sin of Gluttony.
Also, I barely see any male reader x Merlin, so why not write one Because...
Tristan: Hello everyone! Tristan here! Today is the day of the wedding between Y/n and Merlin. Excited right?! I know I am. Well, it's because this is the first time I get to see one. Plus, The Seven Deadly Sins old friends and new ones are coming too! Yes, I know what your gonna say. Tristan! That's a lot of people that are coming to see two people get married!

Holy Crap, that's a lot I didn't even realize! Everyone has been preparing for the last 3 months. And I heard that y/n and Merlin's mother had been keeping an eye on her a lot now. From what I heard, mom saud that she's been sick a lot lately. I hope she's ok today. Also, Dad and Mr. Gowther said that Y/n and Merlin's baby could be at any moment.
