pLEASE I NEED MORE KLANCE HEADCANONS pLEASE
When Keith and Lance finally start dating, they realize that they can’t suddenly stop being assholes to each other because the shock to their system might actually kill them.
So they compromise and keep the rivalry going strong, but now there’s a new undercurrent of… fondness? to all of their interactions.
“Lol this idiot really thinks he can beat me at eating Coran’s food? He’s lucky he’s so cute.” “Haha I can’t wait to rub my win in his face, his pout is so adorable- just like the rest of him.”
And to the dismay of everyone else, they become even MORE unbearable to be around once they’re a couple. Like before they started dating, they used the rivalry as a way of flirting. And it was always very obvious and the rest of the team hated Keith and Lance for making them bear witness to the weirdest pissing match/mating ritual ever, but the team was managing.
But NOW as a couple, every now and then Keith and Lance will be acting as normal when they’ll catch each other’s eyes and then… The team doesn’t really know how to describe what happens, but there’s definitely a shift in the atmosphere. The corners of Lance’s eyes crinkle, the line of Keith’s shoulders relax. Their hands seem to gravitate to each other.
And they just?? Stand there for a moment? And smile at each other? This’ll happen at breakfast, in the middle of the hallway, during a mission briefing- basically everywhere all over the Castle, except for during training.
They stopped being all lovey-dovey in the training room after they once got so distracted while flirting that a training bot managed to shoot Lance in the ass. Lance has never forgotten, mainly because no one else will let it go, so now PDA has been strictly outlawed from the training room (Thank god).
Outside of the Castle, Lance and Keith are very professional about their relationship. There is still flirting; if Lance didn’t flirt at least once a day, he would probably die. But there’s no excessive touching or PDA; Keith is a pretty private person, and he and Lance both agreed that what’s between them is special and the rest of the world doesn’t need to see it.
Bless their hearts for trying, pretty much every third planet Team Voltron visits notices the carefully maintained three inches of space between Keith and Lance and then asks “When’s the wedding?” They tried.
In the Castle though, it’s a whole different story. At first, both boys were painfully shy about being seen doing anything couple-y. If they held hands, it was under the table or behind the back or beneath a blanket/clothes.
After like a month of this, Keith kind of got tired of putting in all this effort to hide something that everyone already knew about so. He went ‘fuck it’ and from then on no one in the Castle has known a moment of peace.
Later on, Keith and Lance both agree it was silly to try and be so private about their relationship, especially since everyone has already seen Lance naked at least three times. (It’s because he likes to change with the door open ‘to let the air current pass through.’ Keith despairs of his boyfriend.)
