Oliver had meant to just try and avoid Percy after he'd practically walked in on him in the morning. He had knocked before entering, but being preoccupied as he was, Oliver was sure Percy hadn't even heard. When Percy spoke to him Oliver nearly dropped the sugar and kept his back turned to Percy to hide the blush on his cheeks.
"Uh, yeah. Help yourself," he said. Most days he left it to Percy to make his own coffee, since Oli himself didn't drink any, but this morning it had been a way to keep himself busy.
