I think this boy may like this girl, so he has this series of actions, and from these actions, I think this boy still likes this girl very much and cares about her very much. Then I think there is another possibility that this girl has done something that makes boys misunderstand and like him, so boys will ask girls if they like themselves. Then the boy thinks he likes this girl, too, and will tell him his job, age, whereabouts and so on. I think these two reasons are basically the same.
