Stucky
Buck, it's not like what you think it is. There's never been a single moment that my feelings for you have so much as wavered. I loved Peggy Carter too. I gave what I had with her up to save the world.
What I feel for you is different. I gave up the whole world to save you. Even now, knowing what they did to me, who they turned me into. All of the lives they made me corrupt or end. All of it was worth it because I did what I came to do. I got you out. If I had to do it all again, I would.
