The girl knew that I liked her, so I invited her to travel with me, and she agreed. Do girls go out alone with boys? Please analyze it?

Being able to accompany you out shows that you occupy a certain position in her heart. At least she trusts you and is willing to go out with you. As for the plot development after going out, it depends on your efforts. This is a situation. Of course, there is another situation where I go out to eat and drink with you, but I get nothing. This kind of person is very scheming and needs to be careful. But I believe she is the first person. Find out, young man.
