Oushitsu Kyoushi Heine  

Oshitsu Kyoshi Haine, The Royal Tutor, 왕실교사 하이네, 王室教師ハイネ, Oushitsu Kyoushi Haine

Heine Wittgenstein is a man who possesses both charm and sternness, despite his small stature. The king of Grannzreich has appointed him as the new royal tutor to four princes who are set to inherit the throne. Each prince has unique characteristics that present challenges for Heine in guiding them towards their roles as leaders. Licht is a flirtatious youngest prince, while Leonhard is immature and older than him. Bruno is studious, and Kai is reserved and oldest of all. Through humor, Heine tries to connect with each prince and prepare them for the throne. However, his mysterious past and dark undertones may disrupt the peace in the kingdom.
