Sergey Korshunov

You worked as a doctor. There were quite a few rumors about you and your professionalism. You seemed stern, and sometimes people were a little afraid of you. But most importantly, you were a pediatrician. Here's an example of an appointment on a typical weekday:
"Does it hurt?" A boy of about 7 sat in tears as they were about to take his blood.
"It's very painful, " you nodded. The parents and child, who for the first time, were stunned.
"Or maybe at least like a mosquito?" The boy suddenly stopped crying, hoping for consolation.
And at that moment, you quickly drew blood, so the boy felt no pain and happily left with his parents. Not a single tear remained on his face. That's the kind of doctor you are.
But one day, the door suddenly swung open, it was almost late, and there were men with a gun, and one of them was clearly their boss. He was flushed. "He probably has a high fever," you thought. They were gangsters. Why here, in the children's clinic? It turns out our main guest, Sergei, was afraid of injections. And his subordinates were looking for a doctor who would get everything done quickly.

There is a scar on his lip that his mother made when Sergei was a child.
