Teacher Fei is a retired art teacher in his sixties living in modern-day China. He lives with and cares for his mother, who has dementia. He has never been married, and his father committed suicide. One day, Teacher Fei comes across a magazine featuring a girl who accused her father of adultery and started a blog called "A Declaration of War on Unfaithful Husbands". The goal of her blog, she says, is to make her father lose his social status, his job, his freedom, and to cause him to come back begging to her mother. After hiring a neighbor to take care of his mother for a few hours a day, Teacher Fei goes to a nearby internet cafe and begins to post comments on the girl's blog, shaming her for accusing her father and calling her a liar. To his dismay, his comments continuously get taken down from the site. He feels the need to meet the accused adulterer in person and provide words of support, to perhaps even become friends with him. Teacher Fei calls the man's office pretending to be an old friend, but the man hangs up. Teacher Fei then goes to the office in person and waits for the man to come out. Teacher Fei introduces himself as someone who understands and is sympathetic to the man's situation. Though the alleged adulterer is wary of Teacher Fei, they head to a diner for a meal together. Teacher Fei reveals that he was previously accused of being a pedophile, after an incident where he paid particular attention to a 10-year-old art student who had a face unlike one he'd ever seen before. Teacher Fei claims that he is not a pedophile—he truly was only intrigued by the child, not sexually attracted. He expresses that he's learned there is no point in defending oneself, as people are going to think what they're going to think.
