VEC-435 It was supposed to be a one-time affair... Rei Aoki had a betrayal with her husband's subordinate who she shouldn't have embraced.

The subordinate her husband brought with her was Takahashi, the person with whom Rei enjoyed a one-night stand. (I couldn't believe she was actually my husband's subordinate...) She must avoid letting her husband find out about their secret relationship. Rei treats Takahashi as if they were meeting for the first time, but... Takahashi, who cannot forget his affair with Rei, is relentlessly pressed. Rei, whose weakness was seized, made a difficult decision to protect herself.
