ガールズ・ブック・メイカー ～グリムと三人のお姫さま 3～

"Dancing is not something you do alone."

Acting prince Eito goes to an ash-covered mansion in the prince-less world of Grimms' Fairy Tales. As soon as he enters the mansion, he finds the character "Cinderella" hard at work cleaning up.

At first glance, everything looks fine, but she's so busy cleaning the mansion, doing housework, and practicing her dance moves that she makes him anxious. Eito decides to support Cinderella as the "acting prince".
