Does it mean anything if when a guy is gonna approach you he smiles really wide?

I have a crush on this guy and when he was gonna talk to me he smiled like really wide like a really really happy smile ( not a creepy psycho smile ofc lol) I heard this means he could like you because he is happy to see you. Because I might be overthinking it and he could’ve just be happy to see me I would still be happy if he considers me as a good friend but I heard it could mean they like you.
