Both characters, besides their relationship, have separate threads.
Marcin’s world (The Blonde) - where he is a vocalist in a punk-screamer - garage band - enters a famous, psychedelic vocalist, Winter.
Nivan’s world (The Redhead) - where he is an ex - hacker wanting to solve the echoes of his own past, cooperates with Rav, a man working for the drug cartel.
Every chapter starts with a title - this is who is the main character in said chapter. If the chapter begins with "The Blonde" it’s Marcin who is the main character in that chapter and if it starts with "The Redhead" the main character is Nivan, and his story is the main thread in that chapter. The titles stem from the hair colors of the characters, which change with time. What you need to remember is that the characters of this story like changes and that both of their natural hair colors is black.
With the evolvement of their relationship, the way they treat each other changes. They refer differently to each other. They cease to be nameless: "Blonde" and "Redhead" to one another. And their names are used more frequently.
The author would like to add that most of what takes place is in Poland, in an alternative city, created for the same role playing game. It’s an immigrant city, housing people of different nationalities and beliefs. This city, if real, would be in the east of the Warminsko-Mazuskie Province and has been named “NoNameCity”
