Oleg was the imagination of Sergei Razumovsky. Razumovsky's dark personality used his image as a cover for his true identity. It was believed that Oleg died in Syria a year before.
the real Oleg is still alive. His death was arranged so that Volkov would join the Squad of the Dead.
He and Sergei had known each other in an orphanage, but because Sergei set fire to the children, Oleg took the blame for him and went to a colony for difficult teenagers, where he learned good combat skills and bomb-making skills and the use of weapons and firearms. having learned that Seryozha became a plague doctor because of his second evil personality and was put in a mental hospital, where he was tortured and pumped with pills because he burned bad people in the city, freeing him from the plague (Oleg did the same thing but in another country), he decided to help Sergei, still harboring warm feelings and affection for him, despite the long separation. Razumovsky's second personality, referred to as the bird, gave Oleg a condition:until he does what the bird wants, it will not let go of Seryozha. He's willing to do anything and leave his job as a mercenary to be safe with Sergei.
