The girl with uncertain relationship asked me to hug the princess and take the initiative to sit on my lap. What is her heart?

That's because she likes you more and wants to confirm her love relationship with you, or because some of your words and deeds make her think that you are already lovers. If she is just an ordinary friend, you should see how she usually associates with other boys. If she is normal and has no intimate contact with other boys, it means that she likes you and has taken you as her boyfriend. If she is like this with other boys, I advise you not to confirm your relationship with her. This kind of girl can be said to be frivolous. Everyone has done it in the thigh. Even if she confirms her relationship with you, it will not change her nature, so there will be a lot of caution, so don't think about her psychology, just know what she is like and whether she is the girl you want.
