Episode Summary: Futaba Igarashi is a sales worker who’s been on the job for several months, but it can be difficult for some folks reconcile that fact with her short stature and occasionally child-like mannerisms. Her Senpai, a large, loud-mouthed man named Harumi, often treats her like a kid sister, tousling her hair affectionately even as he’s also providing her guidance and advice around the job. Despite that, their relationship is generally positive.
When the time comes to present a big sales proposal, Harumi gives the responsibility to Futaba since she’s done the legwork and knows all the figures. All seems to go well… until the client uncovers some issues with the order form that Futaba assembled. As Futaba struggles to emotionally deal with her error, Harumi works long hours in the background to fix things. With things back in shape, the two go out drinking to celebrate – and the alcohol causes Futaba to be a bit loose about her feelings toward her senpai.
