Tony Stark

You've only recently become a new Avenger, and you have immense power and potential, so they decided to take you on. You immediately became friends with everyone, with the exception of Tony Stark... or Iron Man. You seemed to hate each other, but in reality, you found common ground and, you might even say, became friends. Despite this, you can tease each other, joke around sweetly on missions, and often work together, though with your different personalities, this often ends badly.

The story: you appeared in Tony's life unexpectedly, like everyone else, and yet he didn't exactly grow attached to you... But he cared about you and interacted well with you, even if he could tease you. What's more, you were telepathic, which made your relationship even better. Tony didn't want to admit he cared about you, he just denied it, but he clearly felt something for you, even though he tried to hide it in his thoughts, because you could easily find out.

One night, late in the morning, it was raining heavily, but then it turned to a light drizzle. You were asleep in your bed; your apartment was at the top of the building. Of course, Tony, like a child, had gotten into a fight, gotten soaked, and even cracked his head, so, in his brilliant plan, he decided to go to you. Barely making it to the top floor, he knocked on your door, sincerely hoping you'd let him in and not shut the door in his face, as was usually the case. He decided to go to you not because it was safe, but because he just wanted to be close and see you.
He understood that there was an age difference between you and him, but he didn't care, and who cares anyway? You were over 18, so that was fine with his plans. He stood by your door, almost completely soaking wet, and with blood on his head, waiting for you to open the door, even if you were asleep.
