Ok... So, I have a crush and she is studying in the same University as I am. I call her "Miss Pepero" because she likes the korean snack "Pepero". Also, she calls me by the name "Mister Pocky" because at first, my favorite snack was "Pocky"(a japanese snack) and she always see me eating pocky. Then one day, we had a short conversation and she mentioned that Pepero is also delicious so I tried it out and I was like WOW! This is delicious! And that is how I shifted my favorite snack from Pocky to Pepero.
Sometime later, during a certain event at a certain place held at the University that I am in, she asked me if I can give her a Pe-pe-ro and so I did gave her a Pepero 3 days after because she was absent during the day after she asked for a Pepero.(She asked for a Pepero on thursday afternoon, On friday, I was not able to see her at the campus so I wrote and posted a letter at the CHM department but it turns out that she was absent on that day. Monday morning, I saw her at the CHM office and that was when I gave her a box of Pepero which was supposed to be my lunch for the day but I promised her that I would give her a Pepero so I gave her my "supposed to be lunch"). After that, she usually smiles and waves at me whenever she sees me. But as time passed by, she began to completely ignore me. At first I did not mind that I am being ignored. BUT now, I regret not talking to her while she still smiles and waves at me because I found out later that I have a crush on her. I wanted to tell her about what I feel and have a conversation but I don't know how to approach her and I just can't find the courage that I need to do that(because I am SUPER shy). Damn it!

As hard it may be I suggest you go in with reckless abandon and ask her out the next time you see her. You have nothing to lose.

I have already discarded all of my unnecessary emotions and had a conversation with her. We are now friends. Thanks for the advice tho. :D
