Do we know each other before?

After having some thoughts whether to tell YuYan about the truth, Li FuJin had no choice but to respond with a question, instead of answering her.

His attention shifted after noticing the changes in YuYan's expressions. His heart has a feeling of having a roller coaster ride due to his nervousness.

He has no idea what was running in YuYan's mind. Thus, Li FuJin remained silent, watching all her expressions with hope that he could guess what she was thinking before giving an answer.

His mind was a mess while guessing whether YuYan was still on the process of regaining her memories, a memory where they used to be together, but how would he respond if she really did remember 'Li FuJin'?

Thus, Li FuJin decided to ask such questions to have a clue of what YuYan can remember aside for the person having a silver hair.

He wondered, though. Did YuYan remember how looks like? But why would she only ask about a person with silver hair aside from her brother?
