Kostiantyn teaches art and vocals at the Zmina Art Lyceum in Kyiv. On 24 February 2022, the Lyceum was supposed to host a first-grader's Ball, but the enemy had their own plans. Instead of a classroom, Kostiantyn and his wife found themselves in the kitchen – their Lyceum turned from an educational institution into a humanitarian centre for helping the population. The general atmosphere of unity for the sake of victory inspired Kostiantyn to create. Poems were born one after another and eventually turned into a collection of poems, which are now studied with pleasure by his students. "Modern children are more conscious", Kostiantyn says, "and our task is to cherish and support this consciousness by actions for the future of our state."
