Everyone knew it would happen, everyone just waited for it, and when it finally did happen, it was wonderful.
Steve fell in love with Tony really quick. It started with a night they both spent in Tony's bed. Steve had sneaked in without even saying it and nuzzled against him.
He nearly begged Tony to stay. That was the first time Tony realized that behind the Captain, Steve was still alive and probably as broken as he was. He turned around and pulled Steve in his arms, let him sleep and watched him the whole night.
The man was so childlike, so innocent and naive, Tony though that someone had to watch out for him. Make sure that those wonderful qualities did not get lost and that Steve stayed Steve.
For a while Steve didn't talk with Tony until he ended up in Tony's bed another time, Stark pulled him automaticly in his arms, he had been waiting for him, and Steve told him what was wrong.
Told him that he was scared and that he did not wanted to be alone in the darkness anymore. That Tony's reactor was everything he could hold on and that kept his nightmares away and that he did not wanted to leave.
That was when Tony realized that it wasn't true that everyone hated his reactor - Steve loved it, needed it...
"I love you...", Steve said with tears in his eyes when he and Tony had been having one of their typical Get out of my house fights.
Tony stopped yelling immediately and starred at Steve. "I..I love you, Tony...", Steve repeated it, and now Tony understood why Steve was hurt that he had been flirting with someone else, kissing that woman on the party...
He wanted to tell Steve to get the hell out of here, but he couldn't... Instead of that he walked over to the giant baby and hugged him, not saying anything.
"Will you marry me?", Tony asked with a wide smirk on his lips while Steve was sitting next to him with a bowl of Popcorn on his lap. The Avengers were having a movie night, and everyone looked at Tony, Natasha rolling her eyes because she thought Tony was being a dick again, but then Tony asked Steve one more time and the soldier nodded quickly, gave Clint the bowl and hugged the man tightly, placing soft kisses on his cheek. "Yes...Yes I do."
"Say it again, Capsicle~.", Tony hummed against the sensitive neck of his husband, nipping on the skin while grinning. He loved how easily he could drive Steve nuts.
"I..I love you..", he whispered softly and run his finger trough the man's hair, repeating it over and over again until Tony stopped teasing him and they rested next to each other.
"But that...Does not change the fact that I do not want you to waste that much money for nonsense, Tony..."
