What does it mean to send a text message to wake up?

It’s nothing to receive it once in a while. It’s just that the boy is fine for the time being and wants to remind you that it’s time to get up. I used to receive similar messages often, and it took a long time; and later If you call in the morning, it can only mean that they are bored and think of you. Some of them have a crush on you. If you persist for a long time, they will have a crush on you. Occasionally, it means that the boys are just bored.
