Typical love story

I’m 19(Male) under-graduate.I want to confess that when I was in 11th class,I started liking a girl.We were classmates.It was love at first sight for me,if it exists.But I wasn’t able to maintain even good friendship because I was an introvert.She also ignored me many times.My feelings were hidden from her.In 12th,We became good friends.But after 12th,she vanished.I tried to contact her many times but she always ignores me.Finally I told her that she was my crush.But she doesn’t care.I really miss her.
