watIntroducing the "Something Special For Someone Special". It's ring-shaped, it's gift-wrapped, it's basically useless, and it's really expensive ($100!). In short, it's the most accurate simulation of an actual Valentine's Day gift ever made available to the public.
Here's how it works:
First, it's not tradable, only giftable. When it shows up in your special someone's backpack, they can click on it to open a menu that will let them accept your proposal. Once the proposal's been accepted, a message will be broadcast to the entire TF community that will include your name, your special someone's name, and whatever you decided to call the ring. Then presto, the gift turns into two matching diamond bands you can wear in the rain while you smooch up a storm, you crazy kids.
Thats just....really now.
