You can learn Taekwondo from him. As the saying goes, you can get the moon by being close to the water, so that you can have more contact with him and let him know more about you.
Try to choose the same coach as this boy, see when he usually studies, and adjust the time together, so that you two have a chance to get in touch.
Then you can start hitting on him. The first thing you have to do is to let him know about you and have a good impression on you, and then he can continue his pursuit. The first step to make him like you is to dress up. Most men judge a book by its cover. As long as you dress up beautifully, you will attract his attention and make him like you.
Then you should try to say hello to him, nod and smile. These are all ways to say hello. When you get familiar with them, you can ask him to help you correct some gestures. At this time, your attitude should be sincere, just learn from him. Don't let him see your intention at the beginning. Maybe you'll scare people away before you pursue them.
In the process of learning from him, you have more contact and he naturally has a deeper understanding of you.
When you have known each other for a while, you can take the initiative to invite him to dinner and movies. If he is willing to go to the appointment, it means that he has a good impression on you and is willing to associate with you. Even if you don't confess to him, he will pursue you to confess to you in the end.
If he always refuses your invitation under various excuses, don't pursue it, which shows that you get along with him and don't make him like you. If you must pursue him, then show the spirit of stalking. Good men are afraid to follow women. As long as you have perseverance, you will touch his heart sooner or later, but only if he doesn't hate you very much can you succeed.
