Harry realized that he had long since lost perspective when it came to one Gary "Eggsy" Unwin. Not only was he tits over arse in love with man but he was incapable of truly being able to focus on him for any length of time without forgetting things like say how to breath properly, not to mention how to behave like a gentleman or any facts that might come in handy.
Like say how Eggsy takes his tea.
The first time, obviously, how was he suppose to know that he likes sugar in his tea. He makes a mental note to remember for next time. Life has other plans though and he ends up in Kentucky and well, things happen that he wished he could erase.
But then the plans change again. Harry comes back from being shot in the face-he really ought to write a thank you letter to their glasses maker- and he finds that Eggsy is so much more different than what he remembers. More confident, more secure in his role as Galahad and it make things nice for Harry to be able to relax that his protege is making it in the Kingsman service.
He comes to visit after he finally is allowed to know. Harry doesn't blame him for the anger, but readily corrects the guilt and misplaced feelings of having disappointed Harry. Eggsy seems to need the time to get over the hurt and Harry won't admit that he needs to see him just as much.
His doctors have forbade everything but tea and water, unsurprisingly, which is how Eggsy begins bringing Harry tea every so isn't so much a specific time or day, Eggsy is much too busy and Harry does have some therapy. He becomes used to Eggsy grabbing the tea and bringing it to him. He loses himself in their conversations, and let's their friendship bloom under the hospital wing's lights.
It should come as no surprise that Harry becomes the new Arthur. Their lives jump from stagnate to full speed in a matter of days, and Harry realizes all at once that Eggsy has still been trying to get their tea chats back in some kind of rhythm. Many times, Harry will enter his office to see a chilled cup of tea next to an dredges stained empty cup. At first he thinks Eggsy is being lazy just leaving his cup there, but then he realizes that Eggsy was simply letting him know that he had been there.
Nearly a month of missed encounters or half-drank teas interrupted by their lives and Harry can't stand it anymore. He corners Eggsy after his last mission's check up and invites him to dinner.
They drink wine and eat at a fancy restaurant and Harry gives up trying to control his feelings. He loses his excuses about how Eggsy will never reciprocate because he knows now that isn't the point of being in love. He is in love with the younger man and nothing will change that. He loves the way Eggsy speaks all uppity and posh and loves it even more when he lets his accent slip and change and get rough. Harry loves him wear suits that he helps pick out and loves it even more when Eggsy wears jeans and a t-shirt on the range. He gets hot when Eggsy makes a cultured reference and shocks someone. He can admit it, he, Harry Hart, is so far gone on Eggsy that he loses all his good sense.
All good sense.
The next time they have tea, Harry makes the effort. He's getting better at arranging his schedule to have a half hour free whenever Eggsy will be done with his post mission debrief. Being Arthur makes him thoughtful for so many things and never do the details slip his mind. However, when he sets down the tea in front of Eggsy, he knows something is wrong. Eggsy gives him a half smirk and shakes his head.
"Don't you remember I take one sugar, bruv?" he asks, nodding his head toward the bowl of sugar cubes. Harry means to pluck one up and drop it into the cup and ignore Eggsy's growing smirk, but he honestly feels too far gone on the matter.
Instead, Harry leans right into Eggsy's space, noting the way he doesn't draw away even though he can see him moving. He doesn't think, just pressing his lips up to Eggsy's, capturing the bottom lip momentarily before pulling back.
His mouth is obviously beyond his control as he whispers out, "Is that enough sugar?"
Of course then all reason and sense decides to crash in over him and he nearly swallows his own tongue. Why oh why did he just do that!?
But Eggsy just laughs once and shakes his head.
"I think this cup of tea needs at least one more sugar," he replies before pulling him back in and kissing him hard.
If Merlin has to knock on the door a half hour later and ask if Arthur is ready for his next meeting-sending them both stumbling over each to clean up and tuck in shirts and smooth hair and oh god we knocked over the tea pot fuck-well Merlin knew better than to ask.
