A married woman seeks excitement and becomes addicted to online dating, repeatedly engaging in extramarital sex with the men she meets. Her husband, who is aware of the situation, is unable to confront his wife and posts a message on an adultery message board, where he receives a reply from a sympathetic netizen, asking "Isn't that the wife she's with?" along with a video file. During the day on a weekday, the wife is openly having extramarital sex with the man she met on the dating site in the couple's bed. Once the wife gets hooked on extramarital sex, her rampage escalates unstoppable, and she repeats her lewd infidelity.
