Episode 21: Michi Mukai e no ONE STEP!
Yozora: *On the phone with somebody* You two will be here soon, then? All right. Uhuhuhuhu~!
Yozora: *Hangs up* What?
Mitsuo: Hmmmm... You're acting suspicious.
Yozora: Am I?
Mitsuo: Yeah, you most definitely are... Bye★
Mitsuo: *Runs off* HAJIME! SEKKUN! Yozora-san is acting weird!
Hajime: She has been acting weird since Yuki-senpai and Sakutaro-senpai transferred out, hasn't she?
Mitsuo: Why did they transfer out?
Hajime: The island they moved to is an hour away by boat. Maybe that has something to do with it? They haven't stopped their idol activities.
