As a guy, I have many crushes, but it's just a crush. Then, I saw this one girl in school. She's just simple but she has something that makes me attracted to her. I seldom see her at school, like 3 times a week, but everytime I see her, she makes me smile. One problem is I don't know her name and she doesn't know me. We don't have common friends so I thought I'll just admire her from afar. One time while reading in a facebook page of our school, I was about to comment when I thought I saw her pic in one of the comments. I clicked her profile and poof, it's really her. I don't only know her name but also her facebook account. I want to approach her, but I'm kinda shy and she's always with her friends. I really really want to get to know her more. There's a term in our country called "Torpe" which means not expressing your feelings or confessing to the person you like. I'm like that since high school but now I don't want to be "torpe" anymore. I don't want to regret not doing this in the future. I don't want this to be another what if. 

Now, I'm planning on giving her a handwritten letter to like introduce myself to her. Is it a good move? Will she like or appreciate it?

All my friends are saying to take the risk. Should I? Maybe, because she's worth it.
