Исчезнувшая

The protagonist, Semyon, finds himself in a mysterious pioneer camp after the events of the original story, where reality twists and the past and present merge in a nightmarish dance. He is searching for Lena, the girl only he remembers, but the camp seems to be erasing her very existence. Gradually, the world around him begins to crumble, filling with shadows, voices, and inexplicable phenomena. The further he goes, the more he realizes: his own desires and fears might be the key to salvation... or to his doom.

Continuation of Lena Bad End.
