Yuka Aizawa has risen to the position of head of the sales department at a young age. She is a serious person who does not compromise on anything. She is strict with people because she is too good at her job, and although she is kind at heart, she often takes an overbearing attitude towards her subordinates. Kensuke, a subordinate who had been harboring resentment towards her, attacked Yuka while she was alone in the office, knocked her unconscious, and raped her.
