How did they they meet?: They first met when Natsu came to guild. Suffice to say Natsu didn’t leave the greatest first impression.
Who developed romantic feelings first?: Surprisingly it was Natsu. He noticed it around the time the Oracion Seis was put away.
Who is their biggest “shipper?”: All of Team Natsu, but Lucy is the one who puts the most work in. Urging Natsu to ask Erza out on a date and things like that.
When did they have their first kiss and under what circumstances?: It was a complete accident. Natsu and Gray were fighting as usual, when Erza tried to break it up Natsu got pushed into her and lip locking ensued.
Who confessed their feelings first?: Natsu tried, but he couldn’t really get the words out, surprisingly Erza preempted him and revealed her own feelings.
What was their first official date?: Nothing too special, just a walk around South Gate Park and a dinner date.
How do they feel about double dates/group dates?: Erza doesn’t mind them, but Natsu hates dressing up more than once a month.
What do they do in their down time?: Train mostly. Natsu’s goal is to make Erza use all of her armors against him at least once.
What was the first meeting of parents as an official couple like?: Gonna have to AU this one: Igneel was surprised that someone actually took a romantic interest in Natsu but he supported them. Irene was much more open to it. She already started calling Natsu “son”.
What was their first fight over and how did they get past it?: Natsu got cocky and ended up seriously injured on a job. After he was healed Erza blew up at how he needs to stop being so reckless. That was when Natsu realized how different things were now that he and Erza were in a relationship. He has since slowed down.
Which one is more easily made jealous?: Erza.
What is their favourite thing to get to eat?: Cake for Erza, Natsu will eat anything that doesn’t bite him back (and even then he just might eat it still).
Who’s the cuddly one? What their favourite cuddling position?: Erza. She loves it when Natsu’s head rests on her lap.
Are they hand holders?: No, but they do walk close enough for their hands to touch every so often.
How long do they wait before sleeping together for the first time? What’s the circumstances?: It took a little while because Erza has some issues with intimacy, but Natsu was willing to wait. Their first time was a short time after Natsu returned from training for a year.
Who tops?: Sex is another form of battle to them, so they tend to trade positions a lot.
Who does the shopping and the cooking?: Erza does both, but her cooking isn’t the best so Natsu will usually barbecue something every couple of days.
Which one is more organized and prone to tidiness?: Definitely Erza.
Who proposes? Surprisingly it was Erza.
Do they have joined Bachelor/Bacheloette parties or separate? Loke and Cana tried to set something up, but no one was willing. They ended going out themselves and causing more than a few bar fights.
Who is the best man/maid of honour? Any other groomsmen or bridesmaids?: Gray was best man, Mirajane Maid of Honor. Happy, Elfman, Gajeel, Laxus, Alzack, Sting, and Rogue were groomsmen. Lucy, Lisanna, Bisca, Juvia, Kagura, Millianna, and Wendy were bridesmaids.
Big Ceremony or Small?: Erza insisted on small with just the guild and close friends, but Fairy Tail being what it is ignored this request and made it a huge affair.
Do they have a honeymoon? If so, where? Yes, Zeref allowed them a weeks stay at his palace in Alvarez.
Do they have children? How many?: 2. Both of them huge Daddy’s girls.
