Boys have a crush on a girl, but they never send her messages. Is there such a boy? Why didn't he take the initiative to contact, because he didn't want to?

Just because this boy doesn't take the initiative to send messages to girls doesn't mean he doesn't want to. Maybe he is introverted, doesn't like to talk, and doesn't often send messages to people. It is also possible that he has a crush on a girl, but he is not sure whether the girl likes him or not and whether he has a boyfriend, so he keeps her in his heart carefully and silently. Maybe he likes that girl, but he knows that it is impossible between them (family and social factors) and doesn't want to disturb her life.
