What will happen if you continue to thoroughly stir up Kokoro under special circumstances? We call out to couples on the street and have them swap partners with another couple to form two impromptu couples! We make them live together in a closed room for 8 hours! We give them radical game orders from the control room! We periodically forcibly monitor the other person's room! Even though it's a game, her Kokoro explodes when she sees her boyfriend flirting with a strange woman! A battle between women breaks out! They're doing that, but what will you do?
