Mion Sonoda works in the general affairs department of an underwear manufacturer. She has a strong desire to advance and demonstrate her inherent abilities. I was able to transfer to the long-awaited product development department and was selected as a project member for the "new underwear introduction". Until then, she had been sexually harassed by her business partners and senior bosses, and although she was forced to perform imitative sexual acts on herself, she tearfully accepted it in order to be promoted, but the subsequent challenges attacked her... Embarrassed in front of a black company Continuing to endure the shame... will I feel happy someday...?
