Adapted from the book of the same title, this drama is based on an internet incident from 2004. A man (played by Yusuke Santamaria) has married the seemingly ideal wife (played by Yuriko Ishida). But one day, he happens to see a message on his wife's cell phone, and realizes she's planning to cheat on him! She and the other man have arranged a meeting at a hotel, and the husband is torn about what to do. Looking for advice, he goes to an internet forum and asks for help.
