Why does he delete it after I like it?

So there’s this guy who I kind of have a crush on buuuut he has a girlfriend so i dont come between them or message him etc I keep my distance I have liked his videos and pics and stuff I noticed when he makes videos that say hey nice butt or other things right after I like it he’ll go and delete it? And it’s usually after I like them

Lol nah I’m just wondering cause it’s TikTok videos he posts for all girls to see so I’m just wondering why he’d keep them up and then when I like them I noticed they’re gone right after so was wondering if it had something to do with me or just a coincidence
