Emily Rynelle-Eri for short, is a normal high school student, a successor to a long-running family of tea-makers, a young, well-mannered princess hiding behind a spoiled brat's guise, and, apparently, capable of seeing the future. Ever since she could first see the future, she has come to acknowledge the absolute: that she can only see, not change the future. Despite her unique trait, she has led a normal life, made joyful by the Mori siblings she befriended due to sharing the same hobby; Yuuta and Fuyuno. Everything has been well. Until Eri foresaw Yuuta kneeling to Fuyuno's grave in the middle of winter. It is currently October. Snow has yet to come. Eri goes against the absolute.
