But when you strum that iron with your handIt looks like something has changed
-
Based on context in the song, the “iron” is a metaphor that refers to Bocchi’s guitar and we already know that she needs it in her life. Previously, Bocchi only talked about how the guitar is her form of expression, but here Bocchi is saying that playing the guitar has changed “something”. We can infer that that “something” is her feeling of inferiority, that she is powerless and is worst than others in society. Thus, saying that “something” has changed emphasises how Bocchi feels more powerful, or that she has more confidence. This conveys how Bocchi doesn’t just enjoy the guitar, she feels proud about it. This doesn’t necessarily mean that she has no more social anxiety or that she is full of confidence but it does mean that her guitar has impacted her positively.

However if context outside the song can be taken, this cold be more of a reference to Bocchi starting to play in a band. Bocchi have always wanted to be in a band to be noticed and to satisfy her craving for social interactions. Thus, her learning the guitar and joining the band gave her access to the social connections that she desired so much. Thus, learning the guitar didn’t just change her confidence level, but it also opened a whole new world for her and allowed her to make friends.

The connotation of "earth" being a open place is also a juxtaposition to what Bocchi described to be a "dizzying spiral" which is a metaphor for her social anxiety and other issues. This suggest how the guitar allowed Bocchi "explore" more after being confined to the claustrophobic space that is her troubles. This emphasises how Bocchi is not just able to express but learn more about herself learning the guitar, find out her own perks instead of sulking that she doesn't have any that society wants her to have.
Main message of pre-chorus 2 - This pre-chorus further develops and elaborates on Bocchi’s relationship with her guitar, and emphasises how playing the guitar has changed her life. Considering how Bocchi’s main struggle portrayed in the song is her anxiety and inferiority, we can infer that her guitar has changed that by giving her more confidence and sense of self-identity, allowing her to slowly realise that she does have a place in society.
