Ms. Marleen is the English and homeroom teacher for the main characters. She is somewhere her mid-30s, visibly worn down by life and carries a constant sense of frustration and exhaustion.

She puts minimal effort into teaching, often doing the bare minimum while counting down the minutes until the end of the school day. Marleen typically comes across as detached, unmotivated, and perpetually drained.

However, beneath the burnout and cynicism, there are hints of who she used to be. At some point, Marleen genuinely wanted to be an educator, and that part of her hasn’t completely disappeared. On rare occasions, if she believes it will truly make a difference, she’ll push past her apathy and try to help her students.
