What did a senior say, that I was his nobleman? What did you mean?

That is, he appreciates you very much, and after getting to know you, he learns something new from you, which suddenly makes him understand, or has special gains;

It may also be that some of your actions helped him unconsciously, so he said that you are his noble person.

You can pay attention to whether you have done anything recently that makes him feel special or helped him. Maybe it is in study, life, or your personality that has influenced him.

Knowing the time has no special causal relationship with whether you are a noble person or not. Some people you have known for a long time are not necessarily your nobles. ..
