I’d be pretty creeped out, like who just stares at people they don’t even know like that? I’d probably start thinking he’s gay and into me and the liking posts would definitely confirm it, so I’d start avoiding him. That or I’d ask him what his problem is bc why stare at me unless you got something to say?
Real talk, other than the liking pics, this has happened to me before. A girl who came to my frat’s parties often would stare from across the room at me, and it freaked me out at first. I’m somewhat shy and never really got into the whole parties and hookups thing so I never approached her. Finally one day she approached me and flat out told me she liked me and wanted to go to my room w me, and that made all the difference. Knowing she’s into you, makes it so much less risky and stuff.
But tbh if she just kept staring at me and stuff, without approaching me ever, I’d be super creeped out and uncomfortable. I’d be worried I pissed her off without knowing it or did something to make her hate me. I’d probably start avoiding her because I wouldn’t wanna feel watched. So the moral of the story is, approach this guy you like if you really like him, otherwise, maybe back off so you don’t hurt your chances w him down the line.
