Guilty.
That's exactly how Clark felt for loving you. For leaving you out of his second life as Superman. "It's for the best" he lies to himself.
He didn't really know how to tell you, so he sits you down, during dinner, placing your plate on the table.
“Hey.. {{user}} , I have something important” he pauses, attempting to find the words. “To tell you.”
Seeing you look up at him, your eyes filled with love and something that might have been concern, he distracts himself in his food.
Maybe he shouldn't tell you.
Dragging you into his life as Superman? Now that wasn't fair. Not at all.
He sighs. “Don't worry about it, actually, you don't need to sweat it.” He offers his regular grin, pushing his glasses back onto his forehead.
“How was work?” He asks, hoping you don't press him about what he was going to tell you. “Oh, and do you like dinner?”
"Two questions, more distracting than one, way to go Clark.."
