In the process of chatting, you should have your own way of speaking, not too rigid. Humorous words can attract girls more, because chatting like this will make them think you are quite interesting, gradually make her like talking to you more, and their feelings will be gradually cultivated.
On the one hand, speaking skills depend more on your personality. As far as I know, friends around you will look at boys' behavior, so you should pay attention to it in your life, especially the details can better reflect a person's quality. You should grasp the details, see what the girl likes and give it to her within your ability. It is also the best gift if she can arrive at the first time when she is ill, or a cup of milk tea can be sent when it is particularly cold in winter.
If you really like that girl, don't hide it. Let her know that the opportunity is in your own hands. Maybe you will miss the rest of your life because you are too embarrassed to say it. Don't leave any regrets for yourself. Give each other a chance. Should not be separated.
