Spring. After the death of his father – a world-famous artist – left him without any living relatives, protagonist Kusanagi Naoya is put under the care of his friend Natsume Kei’s family. There, his homeroom teacher Natsume Ai, and Kei’s younger sister – the actress Natsume Shizuku – await him in turn. And with the arrival of the new school term, Misakura Rin – Naoya’s childhood friend who transferred long ago – reappears right before him.
Beyond the veil of cherry blossom petals blown by the wind – almost like their promised reunion —
Feelings pile up with the passage of time: once the torrent of emotions comes rushing down, what is the spectacle that awaits?
