Avengers One Shots Part Two!

I'm a fool with (a goose and) a crush

"I didn't even know you two were dating." He said faintly, feeling a pull in his chest and a familiar burn in his throat.

"We've been dating for four years now. Yesterday was actually our anniversary." Sam explained, the smile growing bigger.

"Congrats."

"Thanks. So anyway, 2pm ok?"

"Yeah it's fine, see you then." Bucky quickly left the room, leaving behind his fresh cup of coffee.

Sam stared at Bucky as he hurriedly left the room.

"Weird. And he left his coffee." Sam muttered to himself.

~~~

Bucky managed to get to his room without bumping into anyone and slammed the door shut. Then the coughing started again, the force so violent that he collapsed to his knees.

Blood spattered over the floor, along with the petals. And one fully formed flower. He remembered his research from yesterday and knew that he didn't have long left.

"Why do I have to like someone who's getting married?" Bucky asked no in particular, his voice hoarse. He started coughing again, but thankfully it was only petals.

~~~

Bucky stayed in that position, leaning against the door, until 1:45pm. He forced himself to his feet and go the bathroom where he wiped the blood and petals from him and the floor before going to meet Sam in the gym.

~~~

It was a bad idea, sparring with Sam. Bucky's throat began burning as they started and it didn't stop, it only got worse. Especially when Sam pinned him to the floor.

He was saved by FRIDAY who alerted Sam that Steve wanted him.

"Sorry man, we can spar tomorrow?" Sam asked, picking his water bottle up.

"I'm going to Wakanda tomorrow. But maybe another day?"

"Yeah that sounds good. I'll see you later Bucky." Sam went to leave the gym before Bucky shouted his name, he turned around with a confused look on his face.

"Treat Stevie good, please. He's been through too much to be hurt again." Bucky said.

"Of course, I love him." Sam smiled before leaving the gym.

Bucky frowned and the coughing fit started again. This time, two flowers landed in his hands, looking morbidly beautiful surrounded with the blood and petals.

He went into the gyms bathrooms and tidied himself and the mats up before leaving. Bucky collapsed next to his toilet and coughed up some more petals and blood.

~~~

A few months had passed since Bucky started coughing up petals and flowers and it's been getting worse every week. And it didn't help when Sam and Steve announced their wedding date and plans.

"Hey Buck, can I ask you a question?" Steve asked, knocking on Bucky's door.

"Yeah, sure." Bucky opened the door and his friend walked in.

"Sam's going to ask you to be his best man. I just thought I'd let you know, I know you hate surprises." Steve said.

"Why?"

"You two have been close now, you're like a brother to Sammy."

Bucky nodded before changing the subject slightly. "Who're you asking?"

"Tony. If he didn't hit me over the head, literally, I would've never have asked Sammy out. So I owe him."

"He's a good friend."
