Yasushi Futakao lives in Ginsukimura, a city where it snows for eight months of the year, followed by four months of intense heat. This young man, carrying memories of a past life filled with regret, tries hard to correct his past mistakes. His efforts often don't work out, but things change when he starts his second year of high school.
One day, a new transfer student arrives. She looks a lot like Jingliu, a character from the Honkai Star Rail gacha game. Her aloof attitude and quiet behavior get people's attention, making Yasushi wonder about the secret behind why she's so guarded.
Over time, the barriers between them slowly come down. What starts as just a friendship slowly turns into something deeper. Yasushi, though, starts to feel like something's weird about the world around him. Strange things start happening, making him wonder if the supernatural might actually be real. With his parents and other people looking into progress in quantum technology, the line between science and what can't be explained starts to disappear.
Follow Yasushi as he deals with the tough parts of love, figuring himself out, and a world that might not be what it seems.
