Downstream.

Exploration Stage: Mural House
From: Yuri
Description: On bonfire night, there is a custom of floating candles and wreaths down the river together. The view at sunset is breathtakingly beautiful. Why don't you try it, too?
Completed: Floating a wreath of flowers is also a time-honored tradition. If the wreath floats downstream, it is believed that the woman who made it will be with the love of her life that year. However, if the wreath washes up on the shore, she will have to wait until the following year.
