The survival game (?) in the locked room continues. For some reason, the three start suspecting each other and chaos erupts! “You confessed to Hitomi, didn't you!” “No, I didn't!” “Then who did?!” Their arguments sound like they never grew up past grade school. Embarrassing memories surface one after another, and what should be friendship spirals into suspicion and constant bickering, turning the locked room into a comedy stage. Yet, even as they fight, they gradually share their true feelings, and the distance between the three slowly begins to close. Who is the real culprit? And will their friendship be restored?
