OL Kana no Ojisan Kansatsu Nikki S01E01 - A lot of uncles.

Kana dreamed of being an office lady in Marunouchi, but joined "Bisui Shoji", a wholesaler of small water purifiers for "Maru" Shimomaruko. The company is full of uncles, though it may happen. In addition, it is a sober and classic company that wears uniforms these days. Everything is culture shock for Kana! The uncles, including Mr. Tomioka, who became the instructor of Kana, such as baldness, flatulence, booger, and sexual harassment, were really unique. Meanwhile, a welcome party will be held for Kana. Kana, who is on the verge of collapse, begins to keep a "Uncle Observation Diary."
