In Dr. Feng's eyes, Luan was an enigma.
He thought that he had known the system inside out – granted, he was the one who had built the main source code by hand – yet all of a sudden, he discovered that… he could not even begin to guess what Luan was thinking about. If not for the layer of tight security around Luan which he could not crack, he would have doubted whether this man was telling the truth about his real identity.
After coming clean with each other, their routine did not actually change much. Dr. Feng was still busy with his daily work whereas Luan… well, he was content by settling on the corner of the office and staring into the boundless sea of flowing data.
