My first ever crush and I genuinely don’t even know what to do broooo 😭

okay tis gonna sound really silly but I’m 17 so my parents are calling me a “late bloomer” cause I think I have my first crush?? I keep looking around for this guy, always thinking how to start a conversation with him, and yes, we do interact sometimes in one of my classes cause he sits with me, and I sometimes share my food with him, but he’s social and enthusiastic with everyone so I’m literally no different than the other people he talks to and I don’t even consider myself attractive so I can’t imagine he’d see me the same way 😭 BOIS OR GORLS WHAT DO I DOOOO?!
