JUST a childhood "crush"

When old childhood friends meet again, would you expect a hug? maybe even a few sobs. But when Ayano and her old friend meet, it's a broken leg and syringe to the neck. After Ayano is forced into a conveniently sized music box and brought into her old friend's home, she is tortured (which will NOT be in the main story! another chapter OR MAYBE even book will have those parts for the people who want to know exactly how she was affected!) and after a week, freedom is given! Explore the adventures of a new high school, and a new harem that has formed! Who will Ayano choose? It's a secret.
