The World`s most excellent Hair - S1.E15

Shione-san, vice-president of the Student Council, straightens her hair out from watching a TV program, but everyone else will not listen to her and start coming up with all of these far-fetched ideas. So Shione-san runs back to her house because she does not have to listen to the weird ideas. The next day she is back to her normal hair style. On the way to school, Ayako-san's grandfather calls and tells her that he is coming back.
