Feeling out of place after her mother's passing and her father's remarriage, high schooler Shimana Kameko runs away from home, yearning for a sense of belonging. Her life takes an unexpected turn when she stumbles upon a mysterious man in a kimono at the park. This stranger, Taiyo "Taiga" Fujiwara, offers her a place to stay—but there's a catch: she must fulfill three unique conditions. As Shimana moves into a shared house with an eclectic group of residents, she embarks on a journey of self-discovery, romance, and chasing dreams.

On a seemingly ordinary day, high school student Naho Takamiya receives a mysterious letter from her future self, detailing events that will soon unfold in her life. The letter urges Naho to take specific actions to prevent a series of regrets, particularly surrounding a new transfer student, Kakeru Naruse. As Naho and her close-knit group of friends navigate the complexities of youth, love, and friendship, they begin to uncover the weight of choices and the possibility of changing fate.
