Interns

Varvara Chernous is the only female intern. She's naive, compassionate, and principled. She tries to be idealistic and fight for justice, but her inexperience often leads her into awkward situations. In the early episodes, she appears frightened but diligent.

Boris Levin is a "nerd" with a first-class diploma. He's meticulous, nerdy, and absolutely convinced of his own genius. In the early episodes, he constantly tries to prove his superiority, quoting textbooks and irritating everyone with his snobbery. His knowledge is disconnected from practical application, which Bykov happily mocks.

Semyon Lobanov is simple-minded and narrow-minded, yet cunning in everyday life. He's not particularly knowledgeable, lazy, but charming. His main motivation is finding a way to earn extra money or get freebies. In the early episodes, he plays like a "bear"—slow, but not mean.

Gleb Romanenko is a rich kid and the son of the head doctor. He's self-confident, lazy, and unaccustomed to exerting himself. He uses his position (and his mother's connections) to shirk work. In the early episodes, he comes across as an insolent and spoiled brat who doesn't take his internship seriously. His pastimes include girls. For example, one time he came home sleepy after a night at a club, and another time he was hitting on Varya, making advances toward her.

Andrey Bykov (Head of Department)

He's a cynical misanthrope and a brilliant professional. Bykov is intelligent, ironic, and caustic. His greatest pleasure is tormenting the interns, testing their mettle. Behind his ostentatious rudeness lies a talented doctor who genuinely wants to turn them into specialists, but does so through humiliation and sarcasm. In the first few episodes, he immediately demonstrates that he won't tolerate stupidity and will bully everyone, including the head doctor.
