게 불태우다

burn yourself out giving everything

불태우다 is burning something up, and six of these lines use the same fixed phrase, burning white, which means going until there is nothing left in you. It is how a variety show captions a performance that took everything the cast had, and one line names it directly as the theme, meaning the thing you poured all your passion into. The image is of burning down to white ash.
