A man has been sending me messages, and today he suddenly launched a voice call for me. What does that mean?

This is because this man is not sure enough to say that he likes you. Do you like him? This may also be because the communication between the two of you has not reached the point of expressing your feelings to you. He tells others that he likes you, which is true. Talking to you also confirms this.

In this boy's heart, he likes you, but he is not so sure. The attack on you should be done bit by bit. First, I will chat with you. I'll chat with you by voice after talking to a certain extent. If you accept all this, then he will confess to you next.

In fact, this kind of man still has a certain degree of discretion. At least I'm steady and unwilling to do anything rash. If he gives you a voice, then it is possible that he will tell you directly.

If you didn't answer the voice this time, you must give him this chance next time to see if he said anything.
