If a boy almost never sends a message to a girl, but the girl sends him or her a message.

In fact, we can't just define whether he likes her based on whether he sends her a text message or replies to a text message and then goes to an appointment, whether he is patient with her, and whether he will lend a helping hand when necessary. First, reply to text messages and keep appointments, probably because he respects a girl and probably treats her as a friend, so that's why. Second, patient companionship is probably only because his personality and personality like and can't stand the unhappiness of girls, so it will be like this. Third, the person in need lends a helping hand, probably because he prefers to help others, and he can't see that he likes her. So, these details you said probably can't prove that boys will like this girl. On the contrary, you should see whether he cares more about girls than other girls, whether girls are different from others, whether they treat other girls like her, whether there is anything special, and so on. This is a factor to judge whether he will like this girl or not. The above is my analysis, which may be inaccurate or incomplete, but I hope it can help you. Of course, if you feel good, you can also use it.
