Kazuki Ishii is a background character in somebody else's romantic comedy, and the fallout from Teruhito Amada's love life costs him his life. Then he wakes on the morning of his high school entrance ceremony with all of it still ahead of him. Kazuki's plan for the second run is simple: make no friends, draw no attention, stay a background character on purpose. Meiko Hikata, Amada's childhood friend and the cool beauty the school calls the Ice Empress, has other ideas.
