On my green face, everything is written

Birch in Finnish is koivu - this is the call sign of Simа's new father, reeking of fish, smoked smoke, and fresh grass. And Simа also has a mother whom he loves very much. One day, under mysterious circumstances, she... turns into a transparent water woman with algae instead of hair. How to live on when a family secret constantly looms over you? Thoughts of the future are heavy and distant, like the construction cranes that prick the sky of foreign neighborhoods. But Simа has San Serych Pushkin, a friend of Rupla, and the beautiful Elena.
