The episode highlights the physical toll of constant social performance, culminating in Nagi's hyperventilation episode. Critical Reception

First, Nagi accidentally sees a group chat where her seemingly friendly coworkers mock her naivety and use her as a scapegoat.

She runs her fingers through the curls. For a moment, she winces — expecting shame. Instead, she smiles. A tiny, crooked, real smile. She opens the balcony door, lets the summer wind tangle her hair further, and breathes deeply.

The turning point arrives with brutal, quiet efficiency. Overhearing Katsumi bragging to his coworkers that he’s only with Nagi because she’s “good in bed” and that he’s disgusted by her natural hair, Nagi’s face doesn’t crumple—it empties . That hollow, numb expression is more devastating than any tears. In that moment, hyperventilating at her desk, she collapses. Not from overwork alone, but from the realization that the air she’s been so carefully reading was never kind to her.

: Nagi spends an hour every single morning aggressively flat-ironing her naturally coarse, extremely curly hair. This daily ritual serves as a perfect visual metaphor for her life: straightening out her natural self to fit a rigid social mold.
