Not all people can cope with tragedy. Seven years after her father's death, deciding to face the music, Yamato chooses to come home. But there have been a lot of loose ends that have been left and scars don't heal over night. But unless someone picks up the pieces, what was once broken can never be fixed. Genderbending.
Daisuke's not sure when he started thinking of Yamato as Yamato and not Takeru's brother.
