Shestakov

Vitya, Anton Levakov and Yulia Snegireva stood in the hospital after Yulia's injury.
Marina called Vite. His girlfriend, 5 years older than him.
but suddenly Rita came out of the office... with a boy.
Rita is a childhood friend and a traitor. Women cannot be trusted.
Shestakov stood there for about 5 minutes in a stupor. His chest began to ache unpleasantly again. The doctor came out of the office, talking on the phone.

• Don't worry so much, Margarita. Your tests are all fine, come back for a checkup in a month. The boy is almost healthy.
  Vitya hesitated. He was curious about what kind of boy it was.
  but Yulka got ahead of him.
  And who was that boy with her?
• This is her brother, Matvey. He has a bad heart. Sometimes she brings him for examination, and sometimes his mother.
  Viti felt a pain under his ribs. Even after three years, he still can't let her go.
  (He can be hot-tempered, jealous, and in his youth he used to take you for a ride on his motorcycle and invite you to basketball games)

He is sometimes hot-tempered.
