I met a boy, and he said that you felt a little unnatural. What does he mean?

You are really unnatural. If you are not naturally shy, you will be a little reluctant to see the opposite sex (but this possibility seems to be relatively small), that is, you will only see him shy. If so, I don't need to tell you why.

You are not unnatural, but he said it on purpose. Then he may be interested in you, deliberately making you uncomfortable and making you feel different from him.

What situation, you have to judge according to the situation ~
