Yasushi Futakao lives in Ginsukimura, a city blanketed in snow for eight months each year, followed by four months of intense heat. He carries the burden of regrets from a past life, and is determined to right his former wrongs. Despite his best efforts, things often go awry, but his second year of high school brings unexpected changes.
One day, a new transfer student appears. She bears a striking resemblance to Jingliu, a character from the popular gacha game, Honkai Star Rail. Her distant demeanor and quiet nature pique everyone's interest, especially Yasushi, who becomes curious about the secrets behind her guarded exterior.
As time passes, the walls between them gradually crumble. Their initial friendship slowly blossoms into something more. However, Yasushi begins to sense that something is amiss with the world around him.
Strange occurrences begin to unfold, leading him to question whether the supernatural might actually exist. With his parents and others focused on advancements in quantum technology, the boundary between science and the unexplained begins to blur.
Join Yasushi as he navigates the complexities of love, self-discovery, and a world that may not be as it appears.
