Imagine:
Being sent on a dangerous mission alone but when your life is at stake, Bucky saves you.
PANG!
(Y/N) stood still and held her breath. Slowly she turned around and looked over her shoulder.
Bucky was leaning against the wall and lowered his gun before he gave her his charming smile "You should be more careful, doll"
"What are you doing here, James? This is my mission" (Y/N) sighed and put her gun back in her holster as Bucky came up to her and engaged the safety on his gun "I know, sweetheart but Steve sent me. You were outnumbered"
Mumbling, (Y/N) looked down at the dead agent before she looked back at Bucky "Thank you"
"You're welcome, doll" he kissed her temple.
