Eggsy knew that he had probably the least conventional relationship with one Harry Hart. It came as a bit of a surprise really since Harry was pretty much the most by the book guy Eggsy knew, save for Merlin.
He supposed it really came from how they handled their relationship. They didn't have time for real romance. Long dinners discussing common interests while sipping 200$ bottles of wine were all well and good when they could manage it. However more often it was tea and some takeaway discussing whether the mission in Bolivia was likely to go tits up if Roxy went in alone -it didn't. Or if Merlin would accept a half-destroyed suit as a reason for a mid-mission 2,500$ suit change- he didn't and Eggsy had spent a week trying to get back in his good graces. Incidentally Harry had spent it laughing whenever he saw either of them.
Dates for them consisted of quick dinners and shags, hopefully away from JB's prying eyes-the perv- or lunches with their phones off for 20 minutes and making out while they tried to eat. The first time Eggsy had dropped spaghetti sauce on Harry's suit when the older man had gotten a bit too handsy they learned to keep things above the waist so they didn't make too many messes.
The in-house dry cleaning was a God-send.
Still he thought their relationship was still pretty close to normal in some areas. It had its ups-thank god we survived sex on a plane after Harry had had to join him mid-mission and really there had been a lot of bombs. They had to celebrate a bit. -Or 3am cuddles when Eggsy sneaks in from a long mission when he had been due back two weeks prior- early morning breakfasts where Eggsy always requests an extra sugar and gets two or three if he's quick.- Harry still blushes when Eggsy asks for one prior to a mission by leaning in close and whispering "An extra sugar for the road?"
But of course their relationship also had its downs as well- bullets are still painful as Eggsy learns and Harry's face is devastating when he's spent all night in the hospital wing waiting for Eggsy to stabilize- They fight and argue like any couple- Sometimes over Eggsy doing something stupid or self-sacrificing risky and Harry calling him out on it. Other times it's Harry getting overprotective and unreasonable and Eggsy calling him out on it. Neither argument ends well but eventually they do make up. They remember how much is in their control and loving each other is their choice-Once it got bad enough for Eggsy to take JB to his Mom's flat. Harry had said stupid shit, some reminiscent of what he had told Eggsy the night prior to Kentucky. It had gotten loud and awful and he regretted almost all of it except for how it did put a lot in perspective for Harry. In the end, Eggsy had spent an entire night at his mum's but no more. The next morning Harry had done the gentlemanly thing and begged for forgiveness.
Currently though, Eggsy would have to say that his favorite 'up' moment in their relationship was happening right then. Their wedding.
It wasn't large or conventional. No more people than Merlin, Roxy, Eggsy's Mum and Daisy were needed. Well and a Judge. Harry was standing in front of him with his white suit and black shirt and tie- Eggsy being the reverse a black suit and white shirt and tie. He knew Harry could pull off the white suit better. Harry looked so happy, unable to keep his calm facade up at all he was grinning so hard. The scars from the bits of glass that had gotten around his eye from that bullet so long ago were mostly faded now. Eggsy still couldn't help but reach up and touch them. Reminding himself that Harry had survived and come home to him.
"Now gentlemen," the Judge interrupted Eggsy's thoughts. "I now pronounce you husband and husband. You may now," he spoke grinning too, "give one sugar to your husband."
Harry blushed at Eggsy's sparkling grin, and shook his head. "Come 'ere," he whispers and then leans in kissing his husband for the first time.
Eggsy isn't sure what a conventional relationship or marriage would feel like, but he knows it couldn't feel any better than this.
