Girls say that starting with ordinary friends,

This is normal, because that girl doesn't know you. If she talks to you directly, it means that she has great expectations for you. If she knows your shortcomings in the future, she will be disappointed in you. She mainly gets to know you slowly and lets her know your shortcomings and strengths.

Three possibilities are not excluded:

First, she may like you, but she says so because of the girl's reserve.

The second is that I really don't like you and don't want to break your heart, so I don't know you.

The third kind really wants to start from understanding and take it slowly. I hope you can catch up with her.
