Hosogai, Kei [@kei_hsgi1010] (October 20, 2014). "最近びっくりした事。人気ユーチューバーで、CMにも出たりしているバイリンガール…なんと俺のシアトル時代の同級生笑 週に一回の日本人学校で小学生から高校生までずっと同じ笑 覚えてるかなー?笑 なんか…めちゃ不思議や笑笑" [Something surprising happened recently. Bilingirl, a popular YouTuber, appeared in a commercial. She was my classmate when I lived in Seattle (lol). She's always been the same since we attended Japanese school once a week from elementary to high school (lol). I wonder if she remembers me?
