Can someone such a love doctor help me?

Konichiwa mina!

This would be my first post on this world. But I'll just make it short... And now... I really needed help... On Saturday, it would be the birthday of my crush, and I have a hard time to confess because she is my bestfriend. *o* I am assigned by her parents to make a surprise party for her...*~* I dont really know how to organize a party. I have a hard time to decide if I' ll make the theme romantic (so it would be easier for me to confess) or I'll just make the theme that had something to do with her likes.

I am calling all love doctors :3 to help me with my problem. I know that I cant give any gifts but I wish you'll be willing to help. If you're willing to do so, just send me a PM.

I really needed your suggestions.
