The diary of a young Ukrainian boy

This diary is about a boy, whose name is Yaroslav Litvak. He tells his story about the war between Russia and Ukraine. From the very beginning, he writes how he left for Western Ukraine before the start of the war. He had a good time there with his mother Olena, and two brothers Igor and Lyubomir. And it seems that nothing, according to the boy, should have happened, but on February 24, his life changed forever.
