I have an idea who the friend is- and part of another idea about the shrine. I can't believe I didn't find this before- it's awesome. Plot and fun- a couple odd lines, but heck, does it really matter? :3
I am starting to wonder if the friend was the one who put her in the shrine, or if the result of that friendship's shattering put her in the shrine. I just want to know, and I can't to find out. You have me hooked.
