Yuuto was raised in an orphanage in England. He was taken to Japan after being adopted by Takakura Yoshiomi, an executive of his business.

Yuuto, who couldn’t speak Japanese, was supported by his twin sister-in-laws, the bright and shy Anzu, and the cool and reliable Anri, along with the innocent and gentle Tsubame, and the showy and devious Izumi.

Yuuto’s other childhood friends, Hekiru and Hikaru, moved overseas ten years ago.
They are together with Yuuto again, and their memories from ten years ago return with them.
