A girl said to a boy, you are so cute! What do you mean?

Say you are cute, maybe you are really cute in his eyes, or maybe something you say or something is cute.

Maybe he already likes you, maybe he has a crush on you, maybe he just thinks you are cute, that's all.

I don't think it necessarily means childish. ...

You seem to care about this woman.

Take the initiative and try to figure out the meaning of his words here. What's the point?

Sometimes a word can mean a lot, but sometimes it's just a temporary view and idea, just like now.

I guess he may not remember saying these words or be deeply impressed, but you are here ~ ~

If you care so much about him, let him know.

Don't cling to an irrelevant sentence. Take the initiative!
