Crushing and ready to reach out!!💞

Ive been crushing on this guy at my high school for awhile now. Ive worked up the courage to say hi a few times and he knows who I am. We follow each other on social media. I'm not completely sure if hes interested but in order to find out I think I have to talk to him. I find that it is easier for me to text a new person than to talk to them first. I just need a good way to start an out of the blue convo without seeming to eager and chasing him away. Ive thought about just saying hey but I'm not sure if that would be to random or weird. Please help?
