Was Sayu's Sousou the same Sou?
no~ different Kanji w/ different meaning ^_^
the word "爽" means "refreshing" (the 4"x" in 爽 = "wind" and the "大" in 爽 ="someone spread his(her) arms/legs" , so 爽 means "yay ~ it's so cool and refreshing
") kanji are "easy" to learn (somehow
), they're just drawings ^_^
but the word "蒼" @ Sayu's Sousou means "blue (mood)" ....... a little bit sad
