Guys, Do guys like it when a girl smiles at them?

Well i only see that stuff in anime and movies where the girl smiles with her whole heart at the guy and he starts to blush and look away etc. I just wanted to try that out but only out of fun! So there was a guy in my class we didn't talk much with each other tho and he fixed my phone for me once and i gave him my biggest smile and said thank you and he just stared at me expressionless and didn't say anything, i thought i over did it with my smile lol 😂 but the next days he kept staring, started to tease me for the first time and kept teasing and play fighting with me since then and i started to believe in this nonsense? Do you guys like it? Or is it just a normal thing lol sorry for this weird question tho
