Герой нашего времени (Hero of Our Time) is a novel (from 1840) by Mikhail Lermontov, but you probably already knew that, and if not, check Wikipedia. If you change the й to и, you turn the hero into heroes (an explanation of plurals in the nominative case can be found here), and we’re right where we need to be: with the song (from 2018) with a striking video by НАИВ (or NAIV, Naïve).
