Let's face the fact that Wakanda Bucky is a dandere. He's soft and shy, and basically blushes if you talk to him
You'd be: A) This Wakandan person, whether native or adopted by SoMeOne, or B) You're this CIA agent who gets to tag along with Ross during the Wakanda-opens-up-to-the-world thing
cough cough that's the best thing to do with an OC shipped with Bucky cough cough
You're anyhow amazed at the place. It's not every day you see friendly rhinos, a black panther, a genius princess, and female warriors with Starbucks cups
I also headcanon that Okoye almost quit the Dora unless T'Challa made a Starbucks in Wakanda
And Bucky is on the list of amazing things
The first time he saw you, he was pretty sure he was hallucinating or something, you looked...different than the Wakandans he met
Shuri is the first one to catch one, you guys
"Oh! Y/n! Meet Bucky! He's this brainwashed ass-"
"Shuri!" He gets really flustered
He vaguely might recall you from the area
"Pleased to meet you...Y/n"
He doesn't realize it's a crush till Steve and Natasha and Sam visit, they immediately start teasing (Nat and Sam) laughing randomly (Sam), and giving advice (Steve and Nat)
He shows up with small excuses like 'Um...Zazu the guy from the coffee shop said you missed the coffee break, and I got it for you' and 'Shuri said you have to go back to the lab...you want me to come with you?'
But one night you accidentally hear him while having a nightmare, you were walking outside peacefully. And you heard him, of course, you're a good person. So you went over and woke him up.
And of course, Bucky is god damned embarrassed, and he doesn't sleep with his arm and shirt on.
But you're more worried about him than the arm and the shirt, you ask him a bunch of questions
"Yeah...I'm fine, I'm fine"
As you start to leave the blurts out if you could stay with him. Which makes you stop in your tracks. He curses himself for talking and tries to apologize.
But you accept to his surprise. Why wouldn't you?
He doesn't have to wake up all night. Best sleep ever, and you KINDA cuddle.
It would be an awesome moment to just...say you both really like each other
But! He does come to you when he has nightmares, and you come to him with problems. Ending up spending so much time together.
He can't ask you out, not now, he's afraid of scaring you away, you're his whole world.
But you LOVE him, not like him.
Bucky and you start getting closer, hugs get a bit more common, and he actualy kisses you one time, on the forehead, a surprise for both
Shuri literally is going to die, she's gonna resort to stalking
"JUST KISS ALREADY YOU TWO!"
Also, headcanon that Ramonda adopted Bucky
At this point, every single person in Wakanda ships you two, even the goats seem determined to push you two tougher, literally.
"Uh...I think it's Rumlow...?"
"You named a goat after a HYDRA agent??"
"Rumlow was the first jerk I thought of."
Finally, he asked you out. T'Challa threw a massive party in the palace, Bucky steered away and bumped into you on the top floor of the palace you looked...amazing, as you always did though
So, he manages to get himself together before talking to you
He's still shy, and he's probably gonna ramble for a bit before getting to the point.
"I really like you- Actually...I think...I love you..."
Your brain takes a minute to process it, and he's already apologizing
"I mean, you really don't have to do anything, I just had to put it out there an-"
"It's okay. Cause...I love you too."
