Hello, host, are you a girl? If you are a girl, and a boy asks you if you are free on Saturdays and Sundays to ask you out? In this case, his intention is already very obvious. In this case, he may just want to pursue you. If there is no other intention, he should ask you out on Saturday and Sunday.
And when a boy makes an appointment with a girl, there is no other meaning besides falling in love or pursuing the girl. Or it is impossible for this boy to be bored enough to go out with a girl on Saturdays and Sundays to pass the boring time and make ordinary friends.
And this boy probably also wants to slowly date this girl, and then see if you can develop further. So when a boy asks a girl out, he basically wants to pursue her.
If the poster is a boy, then if a boy asks you out on Saturdays and Sundays, then he just wants to play with you and has no other meaning.
