Does this guys snapchat behavior mean anything?

So I added this cute guy on snapchat and he added me back. He then snapped me immediately after i added him. I snap him back and he doesn't respond. But he continuously snaps me first. He also does it shirtless while flexing. What does this all mean? He also frequently makes eye contact with me and fixing his hair.
