I'm a huge Marvel fan, and also a huge Steve Rogers, Bucky Barnes, and Stucky fan. I've shipped them since I joined the fandom, for multiple reasons.

1. It would bring more LGBTQ+ representation to the MCU, because at this moment, there isn't much. It's seriously so important for people to be able to see themselves in the characters they love, and who better than Captain America himself, who literally represents this country? How awesome would that be?

2. It actually makes sense as a ship, because they clearly love each other and care about each other deeply. They have so much history and shared experience, and Steve would literally do anything and everything for Bucky (and vice versa) Not only would a romantic relationship make sense in their storyline and personalities, it'd be a healthy, lovely, real, relationship. (In other words, this ain't a crack ship)

So yeah. I want that Stucky kiss in Endgame. Or at least some acknowledgement before my boi Steve inevitably dies.
