I used my avatar to communicate with a girl I like (ambiguous stage), and then she changed her personality signature to a crescent-shaped picture today. What do you mean?
It depends on whether she pays attention to interacting with your avatar. Sometimes you think she will interact with you again, but in fact, she doesn't care about this, just likes another avatar. If she is interested in you, it should be that she will pay attention to you and interact with you, instead of thinking about why she did it. Instead of thinking about why she did it, it is better to do more things to let her actively interact with you.
