Help-ish?

As it is well known, Valentine's Day is approaching soon! Normally I ignore said fact but somehow my current crush is making me want to do something for her. The problem is... I'm not ready for her to know about my feelings, so I was planning on going through the secret admirer plan. Now I wonder... is it a good idea?
Right now I can only see advantages, since I'll know what she likes so it won't be bad for her, also, she's been so busy with school that I think this could brighten her day. If she likes it, I'd enjoy seeing her happy knowing I did that. If she doesn't, then I'd at least know that I tried... I can't do nothing else, my own mind is avoiding it, so... What are your thoughts? Other suggestions are well received :)
