After running back to my desk, I tried my best to focus, but because my seat was right next to Erina-senpai's, that thick, humid black stocking foot odor lingered heavily around me, refusing to fade. Behind me, Erina-senpai had already fully immersed herself in her work, looking through her reports with a serious expression, seemingly forgetting her previous embarrassment for the moment. However, constantly stimulated by the strong aroma, my gaze uncontrollably drifted downward once more. I noticed that Erina-senpai had completely slipped out of her other black high heel as well. Now, both of her petite feet were resting freely on the floor, leaving her damp, stocking-clad feet—which had been suffocating all day and night—exposed to the open air to cool down and relieve the swelling ache.
