"Back to Mars" by ​beabadoobee is a song about the complexity of relationships, specifically between two people who may be more than friends but aren't sure where they stand. The lyrics suggest that the speaker and their romantic interest have a history that they are struggling to define and understand. The lines "Ask me again, are we friends or are we something more?/ Doesn't it hurt to think about how we were just before?" highlight this confusion and the difficulty in navigating their emotions.

The lyrics also explore the idea that even if the relationship is uncertain and sometimes volatile, the speaker still wants to be with this person. The lines "Doesn't matter if sometimes we cannot stick to being friends/ Doesn't matter if we break up just to act all fine again" suggest that the speaker is willing to put up with the ups and downs of the relationship because they care deeply for their partner.

The song's title, "Back to Mars," suggests a desire to escape from the complexities of life and relationships and return to a simpler, more innocent time. The lyrics "Take me to the south of France where we could just be old friends/ We'd go to the beach and you could braid my hair/ You could braid my hair" paint a picture of a carefree, idyllic setting where the troubles of the real world can be left behind.

Overall, "Back to Mars" is a bittersweet song that explores the confusion, complexity, and longing that can come with relationships that are hard to define.
