Petals Around the Rose: Fraternity Register

Haha, this was a good challenge, it took me 2 hours pretty much but i got another simple hint from my friend and after trying it for 2 hours i went to sleep but before I slept I thought about it and I found a hypothesis so the next morning (today) I tested it out and it was correct ^_^ Its actually very simple =.= but I was trying to make it harder haha. One thing I still don't understand though is how the name helps with the answer. To me, it doesn't mean anything >.< btw, I'm 16 ^_^
