[Newly established relationship fluff.]
Derek wants to be good at this relationship, he really does, he just feels often that Stiles is constantly out-relationshipping him. When Derek complained about his pillow being too lumpy, Stiles showed up with a brand-new luxury memory foam pillow with a bow on it. Derek cooks Stiles dinner one time and bakes some curly fries from the supermarket’s frozen aisle, the next week Stiles whips up a three-course meal and Derek’s favorite dessert.
And then the random presents start. They’re just little things, like the black licorice Twizzlers that Derek knows that Stiles hates but Derek loves showing up in the glove compartment of the Jeep, and then the laundry detergent brand that makes Derek’s henleys soft and nice-smelling but got discontinued in Beacon Hills (did Stiles drive all the way to Redding to get this?)
So when the Coke bottle shows up in Derek’s fridge with “Share a Coke with Derek,” Derek decides this is it, he’s going to get Stiles the equivalent present or better or so help him.
It’s fairly obvious to him that a ”Stiles” Coke isn’t going to be available in his local Supermarket, so Derek drives three hours to the nearest Coke factory, figuring they’d make custom bottles at the source.
"How long is it going to take?" Derek asks incredulously as the woman adjusts her "Irene" nametag and looks up from her computer.
"Six to eight weeks, now how many hundred did you want?" Irene asks expectantly.
"No, I just want one,” Derek insists.
Irene stares at him blankly. “You’re welcome to buy single cans or bottles of our extensive “Share With” inventory in the gift shop,” she says. “Custom orders start at a hundred.”
Derek blanches at the price.
He’s standing in the gift shop, looking at all the different names, silently fuming when he spots it.
Would it be too soon? Maybe?
Derek buys it anyways so the trip wasn’t for nothing, heart pounding as they ring it up. As soon as he gets back home he stuffs it into the back of his fridge and forgets about it when a kelpie decides to make the Beacon Hills lake its new home, stressing the pack out for weeks.
When the whole kelpie catastrophy is over, Stiles is hanging out at the loft with him and they’re having a Pirates of the Caribbean marathon. It’s nice and relaxing, and Stiles is curling into his chest under his arm, and everything seems perfect. Twenty minutes in Stiles gets up and heads for the kitchen. “I’m gonna get me a soda, you want one?”
"Sure," Derek says.
Stiles is rooting about in the fridge when he calls out, “Derek? What’s this?”
He’s holding the can, the one Derek decided maybe they weren’t at that point yet and it has been a terrible purchase but he couldn’t bring himself to throw out. Stiles brings it back over to Derek on the couch, looking at it in amazement. “Is this for me?” Stiles asks.
"Yeah," Derek says breathlessly.
"I thought you said they weren’t real?"
"That was before you," Derek says.
