Of course I'll bring her candies and flowers, but the pearl of my present is going to be a T-shirt with a painting I will design myself.
You know, this service is quite popular - applying colorful images onto plain T-shirts, and what is going to be absolutely special about this T-shirt is the image I'm going to design myself, that will contain a sweet picture of two of us on the back and a beautiful piece of romantic lyrics I will compose in front of it.
Perhaps it's not going to be as expensive as a ring or perfume, but she's going to remember the verses and the design for years, because I'm going to create a genuine masterpiece of graphical design and poetry putting my entire love for her into it!

Oh boy, isn't it going to be wonderful!
