"Ultimate senpai" is presented as an extraordinary, exuberant person, but the anxiety lyrics contradict this. I think the song is about the strain of trying to keep up with unrealistic expectations. It is simply a persona forced on her when she was growing up, to be perfect, stoic, capable, never showing weakness or complaining. ("But if it's you, Ultimate Senpai, i'm sure you can pull it off") But that is not conductive to healthy mental health, especially for a child. The lyrics tell a story of mental breakdown and alienation ("You're faking it -- "Writhing on the ground everyday without making a sound") Teenagers typically haven't learned to set healthy boundaries yet, her existence revolves around peer approval, at the expense of personal interests ("Clumsily drawing out your dreams")
