The Overworked Tutor? is the thirty-fifth chapter of the Oushitsu Kyoushi Heine manga.
The princes are horrified to discover that Heine's room is a mess, and so they decide to help him clean it. However, since they had no experience with cleaning, they end up making a bigger mess. However, they manage to pull themselves together in the end and tidy up his room, only for Heine to mess it up a few days later due to being a naturally messy person. Meanwhile, the eldest prince, Eins, returns to Granzreich.
