A Troubled Prince!? is the twentieth chapter of the Oushitsu Kyoushi Heine manga.
When Heine comes to Leonhard's room for his lesson, he is very surprised to see him hard at work writing. When asked what he was so focused on writing, Leonhard says that last night, he had a question about his lessons and decided to make a note for himself to ask Heine in the morning, but then as he was writing he came up with more questions and ended up spending the whole night writing them down, Heine admonishes him for staying awake the whole night but applauds his dedication, pleasing him.
Heine decides to answer his questions, starting off with mathematics. Leonhard is still struggling with division and three-digit subtraction. Heine makes a note to review it and moves onto geography. As they were using flat maps to study, Leonhard is confused as to what would happen if one traveled to where the edges of the map were. Heine brings out a globe to explain that maps were only representations of the world, and that the world was actually round. Leonhard then asks why don't they fall off if it was round, so Heine begins to explain gravity before deciding that it was still too early to talk about it, but that they would have a lesson on it soon and he will get a telescope so that they can study the movements of the moon and stars for themselves. Leonhard asks him if it is alright to change his lesson plans, but Heine replies that it is the duty of a tutor to plan lessons that suits their students' needs.
Leonhard confesses that even though he hates studying, but he feels energized when getting the answers to his own questions, and he feels a bit excited to study--something he has never felt before. Heine realizes that Leonhard is slowly maturing, starting to see the joy in learning. Pleased, Heine tells him to keep asking questions. Leonhard then asks trivial questions like "why do carrots and peppers taste so terrible" and "why is dearest brother Bruno so cool?" Heine cuts him off and tells him to ask one last question that has a definitive answer, so Leonhard asks where do babies come from, shocking Heine. Leonhard says that he has always read that they came from cabbages or that they are delivered by storks, but realizes that those stories made no sense. Heine refuses to answer, saying that it is too soon for him, confusing Leonhard. They then start the lesson. Heine tells him to never bring that question up to Licht, which Leonhard is puzzled about as Licht is younger than him.
