Cover art for La La La lyrics by Naughty Boy

The way I see it, the singer is singing about someone who he loves, maybe a sibling or a partener. But this person - we'll call it she - has some sort of mental problem. Sometimes she gets angry and yells and is almost abusive. The singer loves her and doesn't want to give up on her but he knows this isn't going to work.
