He still felt guilty about the fact that he apologized for bumping into Oscar, despite the latter's reassurance.

He smiles at you, holding your hand as you two walk down the street. You were talking about your day, and how it went.

He was still apologizing. For bumping into you, even though it was a small bump. And it wasn't your fault. He was always apologizing. It frustrated you sometimes. But it was also endearing, in a way.
