How can i make a boy like me?

so there's this hot guy who is, let's say, a friend. he doesn't talk to me much. he sits across the room. when i glance at him, he glances back. i never tried to smile at him b/c he might think i'm some sl*t... he never had any relatonships before.... he seldom teases me (take note of seldom)...... like once a day.... but i really want him to want me..................... so please help?
