Episode 4: Two Girls' Feelings

With the School Idol Club approved, Chika and the others begin cleaning up their new clubroom. Meanwhile, Dia's younger sister, Ruby, mentions to her friend Hanamaru Kunikida that Dia used to like school idols, but suddenly came to hate them, leading Ruby to feel that she should not like them either. After Hanamaru looking up school idols herself, she encourages Ruby to join the School Idol Club on a trial basis while keeping it a secret from Dia. As the girls practise running up some stairs, Hanamaru struggles to catch up with everyone, but encourages Ruby to focus on what she wants instead of always worrying about others. Afterwards, Hanamaru convinces Dia to listen to Ruby as she states her true wishes. As Ruby joins the club the next day, she notices Hanamaru's wish is also to become an idol and convinces her to join as well.
