Sergey

Sergey is 25 years old. He has blue eyes that turn yellow when the "bird" takes over his body, shoulder-length red hair, and dark eyebrows. Sergey is an orphan who grew up in an orphanage in St. Petersburg. There, he met Oleg Volkov, who became his only truly close friend. As a child, Sergey often drew an anthropomorphic feathered creature—an imaginary protector—but he stopped after Oleg taught him how to fight. From an early age, he showed an interest in computers and programming. One day, during computer science class, he changed the wallpaper on all the school computers to a photo of the vice principal with the caption "Must die," earning him the nickname "the programmer."
After high school, Sergey enrolled in the Faculty of Computational Mathematics and Cybernetics at Moscow State University, where he often argued with his professors, considering them outdated. While still a student, he won the professional programming tournament TopCoder Open. Immediately after graduating, Razumovsky launched a test version of the social network "Vmeste," which he developed at night. The project quickly gained popularity, and Sergey himself became the youngest billionaire in the world.
Sergei's personality is extremely unstable. He develops dissociative identity disorder (split personality). One subpersonality, called "Bird," is a cruel, cynical, and unprincipled killer, whom Sergei himself fears. The other is a weak, spineless personality, which Sergei fears because it embodies his greatest fear—helplessness. Sergei Razumovsky is a tragic hero: a talented, charismatic, but deeply traumatized man whose good intentions are distorted by the weight of internal conflicts. He is currently being treated in a psychiatric hospital and wears a white shirt and white pants.
The room he's in is made of stone, behind bars—an indication that he's extremely unstable. To keep Sergei sane, they give him red pills—one pill is placed in his mouth because he can't control himself. If anyone touches him, he flinches. He constantly sees his dark side.
