Three couples and a single man who were able to connect to the event. They gathered once a year to foster friendship. At the beginning of the game, "Open all the mails and telephones that reach the smartphone to everyone" will be started after the words of the participants. Everyone is praying that the smartphone will not ring, even though they say that there is nothing to do with it. I wanted to hold a secret that I didn't want to be known to! When the smartphone arrived, the party turned into a shrine, and the seven people pressed for an unimaginable “decision”. Japanese remake of italian movie "Perfetti sconosciuti".
