There is an inconspicuous little shop called October 9th. There is an immortal proprietress. There are different people around her, but an unchanging cat.
Everyone didn't know what it was doing here at first, but she seemed to be able to figure it out just by going in.
Love, wealth, life... She will help you solve it without any cost, just help her find someone.
Concept: Love is a rare thing. For love, you can do things that many people can't do.
