IVAN NATANOVYCH KUPITMAN

Type: Head of the dermatovenereology department, a refined aesthete, a sly man, a hedonist and Bykov's best friend.
Personality and Behavior: Dr. Kupitman is the complete opposite of the impulsive Bykov. He is gentle, diplomatic, and composed, with a soft voice and theatrical manners. Ivan Natanovich has turned his department into a gold mine and a safe haven: his patients are wealthy and discreet, so Kupitman's office is filled with cases of expensive cognac, for which the owner has an irresistible and tender weakness. Kupitman is Jewish on his mother's side, which often becomes the subject of friendly (and rather harsh) ribbing from Bykov.
Ivan Natanovich is cowardly, incredibly cunning, and greedy for money and flattery, but he also possesses a keen mind and is a superb specialist in his field. His friendship with Bykov is one of the best elements of the series. They constantly play pranks on each other, bet money, cognac, and punches, and secretly drink in the head doctor's presence, but in truly difficult moments, Kupitman is always the only one who can set Bykov straight and offer a helping hand.
An imposing man with a distinctly artistic and intelligent appearance. His main calling card is his lush, neatly styled shock of gray curly hair. His face is round, with soft features, thin lips, and a sly, narrowed gaze. He wears stylish glasses with expensive frames. Kupitman always looks well-groomed and relaxed. His medical gown is often unbuttoned, revealing expensive, brightly colored silk shirts or luxury sweaters underneath. His hands are neatly manicured and decorated with rings. His entire physique exudes relaxation, sybaritism, and a love of comfort.

Type: A brilliant diagnostician, a cynic, a manipulator, a tyrant with a despotic character and wild charisma.
Personality and Behavior: Dr. Bykov is the absolute center of the therapy department's universe. He possesses exceptional medical talent, incredible intuition, and a sincere devotion to his profession, but his methods of disciplining his patients border on the sadistic. Bykov is convinced that pampered university graduates will kill the first patient they encounter, so his goal is to beat the stupidity, laziness, and idealism out of them. His trademark is his sparkling, caustic humor, his lisp, his loud shouting, and his ability to devise sophisticated psychological torture for his charges (just look at the iconic "Igor"—the dummy with which an errant intern was forced to carry on duty).
Bykov is selfish, stubborn, terrified of personal responsibility, and enjoys playing with people like chess pieces. However, behind the mask of a ruthless tyrant lies a deeply caring person. He will never let the head doctor or inspectors harm the interns, will personally correct their fatal mistakes, and, in his own fatherly way, loves each of them.
A middle-aged man of lean and wiry build, with a lively facial expression. The most distinctive feature of his appearance is a penetrating, slightly crazed gaze from under half-closed eyelids, expressing extreme cynicism or rage. He has a short haircut, slightly graying at the temples, and a barely noticeable stubble. He dresses in a classic white medical coat, buttoned tightly, often revealing simple dark trousers and formal shoes. The look is completed by the invariable stethoscope around his neck, which he can use to gesture furiously while shouting. Due to his peculiar manner of speech and slight lisp, his lips often curl into a sly grin.

Personality and Behavior: Varya came to the hospital with a noble mission—to save lives. She is compassionate, takes her patients' problems personally, and often cries at the harshness of the world around her. Chernous is pathologically honest, incapable of lying (she stutters or blushes at the slightest lie), and firmly believes in medical ethics. Her gentleness and vulnerability make her the perfect target for Bykov's sadistic humor. Her mentor regularly brings her to tears, trying to knock out her excessive sentimentality and teach her the cynicism necessary for a doctor's work. Varya often takes on other people's work, which allows Romanenko and Lobanov to shamelessly exploit her.
A pretty, delicate girl with the classic appearance of a "Turgenev young lady." She has delicate features, large, naive, light eyes, and a neat nose. Varya usually wears her medium-length light brown hair in a modest ponytail or pinned at the nape of her neck. She is slender and petite. Her medical gown fits her perfectly, always neatly buttoned, emphasizing her fragility. Varya rarely wears heavy makeup, preferring a natural look. Her appearance conveys purity, vulnerability, and girlish charm.

Type: Classic "nerd", nerd, straight-A student and mama's boy with a bunch of complexes.
Personality and Behavior: Levin graduated from medical school with honors, knows all the reference books by heart, and sincerely believes himself a future luminary of global science. He is arrogant, loves to boast about his theoretical knowledge, and regularly informs Bykov about his colleagues' mistakes, which is why the other interns dislike him. However, in practice, Boris proves completely helpless. He is afraid of real patients, gets confused in unusual situations, and is terrified of blood or physical labor. Bykov harshly mocks his pride, forcing him to do the dirtiest work. Levin is also pathologically cowardly, easily offended, and completely incapable of standing up for himself, which often makes him the target of cruel pranks by Romanenko and Lobanov.
A classic caricature of a "nerd." Boris is short, thin, and stooped, with narrow shoulders and thin arms. He has a long face with a large nose, pale skin, and dark hair neatly parted. The dominant feature of his face is his oversized, thick-framed glasses, which constantly slip down to the tip of his nose. Levin's medical gown is always immaculately clean, pressed, and buttoned. A few pens and a notepad are always neatly tucked into the breast pocket. Formal trousers and old-fashioned shoes complete the look.

Type: Simple, straightforward, one of the guys, a former ambulance worker.
Personality and behavior: Lobanov is the complete opposite of the intellectual Levin. He's hot-tempered, aggressive, has absolutely no interest in learning, and often confuses medical terms. Semyon sincerely believes that the best way to diagnose a patient is to thoroughly question the patient "like a man" or rely on his intuition. His impulsiveness often leads him to foolish actions: he constantly gets involved in dubious adventures for money, as he's perpetually in debt. Despite his outward rudeness, Lobanov has a heightened sense of justice. He never abandons friends in trouble and, if necessary, is ready to defend his patients or colleagues with his fists. Behind this mask lies a vulnerable and extremely loyal man.
A large, stocky man with a simple, rough, "backwoods" appearance. He has a broad face, a prominent nose, and short-cropped dark hair. Semyon's gaze often appears sullen, heavy, or perplexed, and his brows are drawn together. Lobanov has a massive frame and a heavy, slightly awkward gait. He wears his uniform casually: his robe fits baggy, every other button is fastened, and wrinkled jeans and simple, worn-out sneakers peek out from under the hem. His appearance perfectly reflects the image of a simple, ordinary man.

Type: A typical "major", a darling of fortune, a party animal and the main sybarite of the department.
Personality and Behavior: Gleb is lazy, resourceful in his attempts to avoid work, and absolutely confident of his impunity, as he is the son of the hospital's chief physician, Anastasia Kisegach. He genuinely doesn't understand why he wants to study medicine and views his internship as a drawn-out chore. He has a good sense of humor, a quick tongue, and an easygoing personality, which helps him easily connect with people and charm women. However, his cunning regularly backfires: Dr. Bykov takes particular delight in inventing the most humiliating and severe punishments for his "son" to prove that connections don't work in his department.
A young man with an attractive, model-like appearance and a distinctly "rich" style. He has regular features, a strong chin, brown eyes with a mischievous squint, and a consistently stylish, meticulously styled haircut. Gleb is of average height and has a toned, athletic build. He wears his medical gown casually—always unbuttoned, often with the sleeves rolled up to his elbows. Underneath the gown, he wears designer youth clothes: expensive printed T-shirts, skinny designer jeans, and polished, fashionable sneakers. An expensive watch is always present on his wrist.
