🏥💉/Interns reaction

Margarita Pavlovna Koroleva (Yulia Nazarenko-Blagaya) is the new head nurse, appointed to replace Lyuba, who left (starting with episode 150). She's quick-witted and cool-headed, and Bykov's former lover.

Lyubov Mikhailovna Skryabina (Svetlana Permyakova) is the head nurse of the therapy department. Experienced and efficient, but talkative and prone to gossip. In episode 149, she left for America to join Levin for two months, but later returned.

Phil Richards (Odin Byron) is an American intern from Boston who came to Russia on an exchange program in place of Levin.

Semyon Semyonovich Lobanov (Alexander Ilyin Jr.) is an intern. He's not the brightest, but he keeps his cool in emergency situations.

Gleb Viktorovich Romanenko (Ilya Glinnikov) is an intern, Anastasia Kisegach's son from her first marriage, and Bykov's stepson. He has a reputation as a "rich kid": he frequents clubs and treats women like a consumer. He is Lobanov's best friend. In episode 179, he became a doctor.

Varvara Nikolaevna Chernous (Kristina Asmus) is an intern. She's diligent and proactive, but sometimes too naive and doesn't understand hints.

Boris Arkadyevich Levin (Dmitry Sharakois) is an intern with honors. Meticulous and tedious, he has few friends and is nicknamed "Lenin."

Ivan Natanovich Kupitman (Vadim Demchog) is a dermatovenereologist, a PhD candidate, and the head of the dermatovenereology department. He is Bykov's best friend. He is cunning, self-serving, and fond of expensive cognac. In his work, he considers himself a "priest of Venus, the goddess of love," but in life, he is a philosopher of everyday life.

Anastasia Konstantinovna Kisegach (Svetlana Kamynina) is the hospital's chief physician. She is initially Bykov's mistress, then his wife, and the mother of his child. She has a strong character, but can also be sentimental at times.

Andrei Evgenievich Bykov (Ivan Okhlobystin) is the head of the therapy department and internship supervisor. He's an excellent specialist, but has a very complex personality: cynical, sarcastic, and possesses a peculiar sense of humor. He was once a biker nicknamed "Lizard."
