There was a girl who replied quickly when she sent a message for the first time, but she didn't reply after one or two. What do you mean?

I can only see that you care about her. There are many reasons for this. If it is a relationship between men and women or it is about to develop into a relationship between men and women, then in this case, 1 means that she is really busy and has no time to reply to you. She is thinking and doesn't know how to answer you. Wait a minute, wait a minute. 3 is the most intuitive, she doesn't like you, so she's too lazy to perfunctory. . . .
