Does this represent a hint?

Assuming that she is a girl who has no heart, it means that she is interested in you, but it is not deep, depending on how you react. This is a conservative approach. If you don't accept her, you have to avoid it, and if you accept it, you have to confess it, so that no matter what the result is, the girl's face will not be damaged, and don't keep others waiting for too long (it is also possible that people are very kind to others, so you can observe whether she will treat others like that).
