make him/her try to express his/her shyness. these shy people have also very good friends which they're not shy with. why? because these people know her/him very well. so you must be very open and make him/her open to you about her feelings. force her/him to tell if it's necessary. :)

say hi and ask him/her out. life is too short to consider other options ;-)

I had this situation before. I talked to them, asked them their interests, tried to make them feel more comfortable around me so that they could open up and not be shy. It worked! Just try and make a conversation. Find something they're so interested in that they enjoy talking a lot about it. Then once they are more comfortable talking to you, ask if you can hang out with each other sometime.

I will write a love letter or a song for him~~~~~And give him a kiss~~~~~Then my teacher will slap me...TOT...

I am very shy myself, so I'm not sure.. (:
