The title, Zuko, references the character from popular cartoon series, Avatar: The Last Airbender.

Zuko’s character arc throughout the show is one of a royal firebender transitioning anger due to neglect from family and friends, into redemption and peace once he had found his true self and was appreciated by the new people around him.

This parallel can be drawn in the outro especially, “prior to all of this fire they didn’t wanna know…”, the fire he is referring to is both Che Lingo’s own lyrics and bars, but also the fire used by Zuko in The Last Airbender. Maybe Che never felt like he was appreciated or felt the love he deserved until he started making a name for himself in the rap scene.
