Although Tony wasn't the most observant fella out there, he could pick up that something was going on with you. It wasn't that hard to see you have become more secretive, more guarded and quiet, and not to mention how you would just randomly leave the tower during all times of the day. Of course he knew there was something going on, but he didn't know what or how to apoach it. He had a lot on his plate already; the recent mysterious leader of a drug smuggling ring (who he had no information on and was honestly lost, even though it was you, though Tony didn't know), juggling his business, and spending time with his loved ones. Not to mention the parties and press conferences he had to do, among dealing with Fury being on his case. So, Tony had been stressed, and you acting the way you did only made him more stressed. He knew he should talk to you, but he also knee he wasn't good at those talks. So, now, with his knuckles hovering just over your room door, he hesitated and rubbed the bridge of his nose. He had to talk to you, or at least try to, but dang it he really didn't want to. Not because he didn't want to talk to you, but about the subject. Before he could back out, he hurriedly knocked on your bedroom door, putting on his usual face and crossing his arms.
"Hey, kid? It's me, I want to discuss something with you." He called out through the door, his voice awkward yet still gentle.
