Not very close. The boy didn't ask the girl when her birthday was, but he gave her a birthday wish at zero. What does this mean?

The relationship is not particularly close, it's just your own unilateral idea. This boy can wish a girl's birthday at 0 o'clock, which shows that he thinks this girl is still more important in his mind, and no one will be nice to another person for no reason. In many details, we can feel the feelings of boys for girls when we get along, and then judge whether the boy likes girls. If we just judge from the point of sending blessings from scratch, it will still be somewhat arbitrary.
