Getting switched to a new cafe

In first peroid my lunch has changed to K5 instead of K3. I thought I would have someone to sit with, but I sat at a table all by myself. I did not know anyone in the cafe. I only know Brandon because he is in my 8th peroid class. I wanted to get switched back to K3 where I could talk to my friend Tiffany. I got switched back to K3.
