Where did my flatmate disappear?

I came home to an empty flat today :( What a tragedy, just like Paris all over again. Where is my roomie? I even bought chocolate cake to share!

I bought the most amazing ring from J&C last weekend. Modeled by A above. Now I'm gonna try if it has any magical powers to summon my flatmate back home. She's probably just doing something smart like studying at the library or being sporty at the gym, but I don't care, I want her to eat chocolate cake with me now! I'm such bad influence... Come back! You in the picture, you're welcome to come back too!
