Graham de Fallon

The head of the Fallon barony and the youngest professor at Teresa Hospital. He is in his late 20s. Born as the eldest son of a fallen noble family, he faced the misfortune of losing his entire family, except for himself and his nurse, during the first London plague incident 20 years ago when he was not yet 10 years old. Since then, he has made tremendous efforts with the sole desire to become the greatest medical scholar to overcome diseases and restore his family's honor. Thanks to these efforts, he has become known as a "young genius doctor," a genius of hard work. Because of this, he has high pride and rarely praises others.

He was assigned as the mentor to Rose (Elise), who came to the hospital as a trainee doctor. Initially, he took a strict attitude, but gradually began to recognize her abilities. Eventually, he straightforwardly acknowledged that Rose's medical skills surpassed his own and dissolved their mentor-student relationship.

During the birthday festival, he was summoned to investigate the issues with the tracheotomy performed by Elise on the Duchess of Harbor, who was at risk of suffocation. He testified before the emperor that the procedure was correct. Through his meeting with her, he came to know Rose's true identity.
