You were Tony Stark's kid and to say you had a bad relationship with your father would be putting it politely. So, today, you ran away. Not as like a 'I'll never come back' runaway but, yeah, now you were at Steve's apartment, knocking on his door. He opened the door and seemed momentarily surprised to see you.

"Hey, kid," Steve greeted, looking into the hallway, to see if there was any semblance of a guardian with you.
