Between March and May 2004, an anonymous user posted in a sub-forum for single men to decry his woes. His post detailed an event that had happened that day as he was riding the train. According to his account, he was sitting on the train when he noticed an attractive woman. Suddenly, a drunken man entered the car and bothered many passengers, who did not offer any resistance to his disturbance. This man then began to sexually harass the woman, and seeing no-one else coming to her aid, the poster told the man to stop bothering the woman. The two struggled for a short time while the other passengers used this distraction to call the conductor, who took control of the situation.
This poster was an extremely introverted, socially inept otaku. Never having done such a thing before in his life, he was amazed to find that the woman was thanking him deeply for saving her from harassment. They exchanged addresses and parted ways. The poster, upon returning home, began talking with other posters in the thread and was nicknamed "Densha Otoko" (電車男?) ("Train Man") for his bravery.
A bit later, Densha received a package from the woman he had saved. This package, originally thought to be a generic thank-you gift, turned out to be an expensive tea set. Flabbergasted, he turned to the 2channelers for advice: he was convinced that such a gift was too expensive to be a mere thank-you gift. Densha then contacted the woman and began meeting her regularly, all the while posting updates on 2ch and discussing the matter with other posters. Following their collective advice, he got a haircut, purchased new clothes, and began to come out of his shell. After seeing her for a while, his personality had changed and this culminated a few months later in Densha confessing his love for the woman. She accepted and when the 2channelers were informed of this there was a mass celebration; posts began flowing in congratulating the new couple.
Because 2ch has an enormous impact on net culture in Japan, this story quickly spread throughout the media and became an instant hit. Its almost fairytale-like simplicity and emotional power drew people to the story, and a copy of the original threads relating to the story was published in a book. Since then, there have been four manga adaptations of the story; a feature film which reached No. 1 in the box office upon its release; and a hugely popular TV live-action drama aired during 2005. According to Densha Otoko and Hermes (the nickname of the woman; named after the brand of the tea-set she sent him), they are still together
