There is a person who always sends him a short message to reply quickly. He won't send it to you without texting. I don't know what to do next!

He came back quickly, maybe it was his habit, or maybe he really liked you. In short, he doesn't like it, or he's too lazy to reply to you. If you don't take the initiative, you may be introverted. Then you should take the initiative at this time. In fact, you don't have to show your attitude. This is how you get along. For example, if two people are together, if he likes you, he will take the initiative even if he is introverted, because love is out of control. If he has no passion, or even an indifferent attitude, he doesn't like it.

See, getting along face to face is the best way to see a person's heart.
