恋風

Koshiro Saeki, freshly dumped and adrift, returns a dropped train pass to a bored high schooler named Nanoka Kohinata, and the two spend an afternoon together at an amusement park. That evening, when their father arrives to pick Nanoka up, Koshiro learns she is his younger sister, separated from him since their parents' divorce and newly arrived in Tokyo to live with them. Unable to shake the connection they made before either knew the truth, Koshiro is left navigating an attraction he can't easily set aside.
