Ye Xiao was talking tactfully. He denied that he had met Master Bai before, and at the same time, raised his status. [You may be the top attraction and the most powerful person, but I don't want to be tuft hunting. Trying to get close to a man in high social position just because of a feeling is disgusting!]
He then smiled bitterly and said, "Please don't laugh at me. I am always retentive. In fact, I once called myself the most retentive person in the world. Normally if I met someone, I would never forget him. It would never be just a dim image. Master Bai, you are such an outstanding man… If I have met you before, I wouldn't forget.
"However, I just feel like I know you. I don't think I can remember where I have met you in the past. That is weird. You said we met before. Could you please give me a hint? Maybe it would remind me something."
Ye Xiao frowned and looked troubled like he was thinking so hard.
