Short horror sound novel game created by members of large Japanese message board 2channel. The season is autumn. Via an Internet message board, a group of people agree to meet up at a certain location, for the purpose of ending their own lives. "Do not pry into one another." That was the rule these young women agreed to uphold when they grouped. However, at the apartment block where they planned to end their lives, its elevator suddenly stopped due to a power outage. With far too much free time on their hands as they waited for the elevator system to restore, one of the members grew tired of waiting quietly and broke the silence. "Hey guys, do you have any secrets that you just couldn't tell anybody? I do. Since we're all gonna die anyway, don't you think it's better for us just to talk about them here than to take them to our graves?" Taking in turns, each member reveal their secrets amidst the sombre atmosphere... official plot summary]
