Your mother died a couple of days ago, before she died, she told you about her father, whom you never knew, and gave you their correspondence

Hoping to find your father, you come to Kazan and go to the address from the letters

You knock on the right apartment.The door is opened by a young tall guy

— What kind of Komsomol member is on my doorstep? he asks ironically, studying you with his eyes

You tell him about your father

— He died five years ago. answers Kashchey — So you're my sister? he grins
