The best girl in the world

People with naturally different colored eyes are rare, making up only one percent of the planet. But Ulyana Kovylka considers her appearance a curse: at school, she was nicknamed a witch. If Ulyana gets offended by someone, her blue eye turns blue, while her green eye becomes dark emerald, almost black.
By chance, while at the Literary Museum, Ulyana notices a figure of Buratino among the exhibits, as it watches her intently. That night, Ulyana dreams of the museum curator, who tells her that Buratino has gone missing. Immediately after, the curator disappears as well. Ulyana finds herself in a series of tangled events and will have to save not only fairy tale characters but also her friends!
