Shunsuke Kawamura worked in a real estate company and was always the best of the best when it came to sales. He was going to marry the daughter of the CEO of his company, but then, something unexpected happened… Just before the day of his wedding, he attended a surprise party held by his colleagues and got drunk. On his way home, he accidentally fell into a deep manhole. By the time he woke up, it was already midnight. What was even worse was that his right leg was heavily injured and he could neither contact the police nor find out his current location using GPS. The only person he could contact was his ex-girlfriend, but she did not believe in his words. He started to believe that he might have been set up by someone, so he decided to set up a new Twitter account named “Manhole Girl”, hoping that with the help of the internet, he could locate himself and call out for help. Netizens excitedly assisted him to search for the suspect.
