I NEED HELP FAST PLEASE ?? IM DESPERATE?

[A]

How to show a cute stranger guy i like him indirectly if im shy??
I have had a crush on this guy for a year now and he doesnt know i exist. Hes a year older than me and this is is his last year at school. Im 16 and shy. Nobody knows i like him and i dont wanna tell my friends. I only see him in the hallways in the school but not often. He. never even looks at me. I cant just go up and talk to him. How do i indirectly show him i think hes cute? Im even scared to smile cos im so scared of rejection? How do i get him to notice me without being really obvious? Is there any video abou this on youtube or sth? I have zero guy experience and im socially awkward around new people!
P.s. i dont wanna drop anything in front of himor bump into him. also no friends involved
Thanks in advance
