The Letter She Kept Waiting For

Kept Waiting For A Response is a PV-less song released in the album Triangle vol.1 by K-Books. It is believed to be part of the Story of Evil and take place many years after the events of The Daughter of Evil, due to the fact the characters and setting appear to be similar, however it has not been confirmed. The song tells of an orphan who lives at an orphanage, helped by a kind nun.

Plot
The nun was getting old and her health has started to falter due to a disease. The orphans whom she was taking care off wanted to repay her for her kindness towards them, offering to grant any wish she has. She tells the orphans that she had sent a letter out to sea and was expecting a response for a very long time, even though it may never come. Desperate to grant her wish, the orphans traveled far and wide and ended up finding an old painter who tells them all about who that nun really was and that the person who was to receive her letter is no longer living.

On her deathbed, the nun was given a fake letter in response to her letter by one of the orphans. She merely read it and said "Thank you", just as she dies.
